Taking an Incheon Airport limousine bus with two large suitcases? Before heading to the bus stop, check both the number of bags and their size. A suitcase accepted by your airline may not automatically meet your airport bus operator’s baggage rules.
Incheon Airport’s general luggage guidance allows up to two smaller suitcases or one larger suitcase per passenger. However, individual bus companies have their own weight limits, size restrictions, and excess baggage policies.
Quick answer: Check your bus route and operator first. Then confirm the number of suitcases, the actual dimensions and weight of each bag, and whether an extra luggage charge applies. Paying an additional fee does not automatically guarantee that oversized baggage will be accepted.
This guide compares Incheon Airport’s general advice with the published rules of Airport Limousine Co. and K Airport Limousine, including routes such as 6001, 6015, and 6701.
How Many Suitcases Can You Take on an Incheon Airport Bus?
In October 2025, Incheon International Airport published an English-language guide explaining its general airport bus luggage limits.
The airport’s guidance separates luggage into smaller and larger suitcase categories.
| Suitcase Size | Incheon Airport’s General Guidance |
|---|---|
| 20–25 inches | Up to 2 suitcases per passenger |
| 28–32 inches | Up to 1 suitcase per passenger |
| Over 32 inches | Not accepted under the general guidance |
| Weight per item | Less than 20 kg |
For example, a passenger with two 24-inch suitcases may fall within the airport’s general allowance. A passenger carrying two 30-inch suitcases should not assume that both will be accepted.
The airport also explains that non-suitcase items, including boxes, golf bags, and musical instruments, may count toward the luggage allowance.
Important: These are general airport guidelines, not universal conditions for every limousine bus. Incheon Airport specifically advises passengers to confirm the rules with their actual bus company.

Do Bus 6001, 6015 and 6701 Have the Same Luggage Rules?
No. Airport limousine buses serving Incheon Airport are operated by different companies, and their baggage policies are not necessarily identical.
For example, routes 6001 and 6015 are operated by Airport Limousine Co., while routes 6701, 6702, and 6703 are operated by K Airport Limousine.
This distinction matters when traveling with a 28-inch suitcase, multiple large bags, or luggage weighing more than 20 kg.
Airport Limousine Co.: Routes 6001, 6002 and 6015
Airport Limousine Co. operates several Seoul airport bus routes, including 6001, 6002, and 6015.
Its April 2026 passenger notice gives a standard baggage allowance of two pieces per passenger, with each piece normally under 28 inches and under 20 kg. It also specifies a combined external dimension limit of 158 cm.
The company’s English transportation terms describe a similar two-piece free allowance but use a dimensional limit of less than 160 cm per item.
The operator’s FAQ also discusses carrying one suitcase larger than 28 inches, while its newer passenger notice includes a separate provision for one larger or heavier item per passenger.
Because these official documents use different size and weight descriptions, do not assume that every suitcase over 28 inches or 20 kg will be accepted. Confirm the exact dimensions and weight with Airport Limousine Co. before travel.
Airport Limousine Extra Luggage Fees
Airport Limousine Co.’s April 2026 passenger notice lists a charge of KRW 8,000 for each item exceeding the free baggage quantity on its Incheon Airport services.
Its FAQ also describes this amount as approximately 50% of the passenger fare for additional luggage.
However, an extra fee does not necessarily override restrictions on the item’s size, weight, safety, or available luggage compartment space.
Carry-on bags may also be included in the operator’s baggage count. Do not assume that a large backpack or duffel bag is automatically excluded because you plan to bring it inside the bus.

K Airport Limousine: Routes 6701, 6702 and 6703
K Airport Limousine operates routes including 6701, 6702, and 6703.
Its official English FAQ states that each paying passenger can carry up to two baggage items with a combined weight of up to 40 kg free of charge.
However, this does not mean that one suitcase weighing 40 kg is automatically accepted.
The operator’s FAQ also includes a 20 kg individual baggage threshold in its refusal guidance. Its conditions of carriage describe a 50 × 40 × 20 cm limit for items carried inside the passenger compartment.
Because the published wording for baggage refusal and cabin items can be confusing when applied to large suitcases stored below the bus, travelers should confirm the acceptance of unusually large luggage directly with K Airport Limousine.
For baggage exceeding the free allowance, the company may charge an additional amount of up to 50% of the passenger fare per qualifying item, subject to its conditions.

Can You Take a 28-Inch Suitcase on an Airport Limousine Bus?
A 28-inch suitcase is included in Incheon Airport’s general category for larger luggage, but individual operators may apply more specific limits.
For example, Airport Limousine Co.’s standard published conditions use wording such as “under 28 inches” and a maximum total external dimension.
A suitcase sold as 28 inches may have a different actual outside measurement once the wheels, handles, and expanded sections are included.
Before traveling with a large suitcase:
- Check the manufacturer’s published external dimensions.
- Measure the height, width, and depth of the suitcase, including protruding parts.
- Add the three dimensions together if your operator uses a combined measurement.
- Weigh the packed suitcase separately.
- Check the operator’s baggage policy for your exact route.
Do not rely on the advertised inch size alone. The bag’s actual dimensions and weight are more useful when confirming whether it can be loaded.
Check Your Bags Before Leaving the Hotel
The simplest way to avoid a luggage problem at the airport bus stop is to check your bags while you still have time to adjust your transportation plan.
Start by weighing each suitcase separately. One heavy bag may exceed an operator’s individual limit even when your total luggage weight is below the combined allowance.
- Count your bags: Include suitcases, large backpacks, duffel bags, and other items the operator may count.
- Weigh each suitcase: Check individual weights rather than relying only on the combined total.
- Measure external dimensions: Include wheels, handles, and expanded compartments.
- Find your bus number: Identify which company operates the service you intend to use.
- Check unusual items: Confirm the rules for golf bags, strollers, musical instruments, bicycles, or large boxes.
For example, a traveler with a large suitcase and a substantial backpack should not automatically assume that the backpack does not count as luggage.
If your baggage is close to a published size or weight limit, check the operator’s current conditions before leaving the hotel.
What Happens If You Have Three Suitcases?
Three suitcases may exceed the standard free allowance for one paying passenger, even if each bag meets the individual weight limit.
The outcome depends on the bus company and the luggage involved.
1. You May Need to Pay an Extra Baggage Fee
Some airport limousine operators allow additional qualifying luggage for a surcharge.
For example, Airport Limousine Co. publishes an extra baggage charge of KRW 8,000 per item beyond the free quantity on its Incheon Airport routes.
Other companies may use a different fee structure, so do not apply this amount to every airport bus.
2. The Bus May Have Limited Storage Space
Airport limousine buses have luggage compartments, but available space can vary depending on the vehicle and how many passengers are traveling with large bags.
Even when an extra baggage fee is published, acceptance may still be subject to the operator’s storage and safety requirements.
3. Oversized or Overweight Items May Be Refused
An extra fee should not be treated as permission to carry luggage that exceeds the operator’s permitted dimensions or weight.
If two travelers have three suitcases between them, check the allowance for each paying passenger rather than assuming that baggage allowances can always be transferred or combined.
Travelers carrying several large cases may find a prearranged vehicle more practical. Our guide to booking a large taxi in Seoul for groups and luggage explains how to check vehicle capacity before arranging transportation.
How to Find Your Airport Bus Operator
Your bus number is the easiest starting point for identifying the company responsible for your baggage.
Incheon Airport provides an English bus route search, while the airport’s bus service information also lists major routes and operating companies.
- Find the number of the airport bus you plan to use.
- Open Incheon Airport’s official English bus search.
- Use the Incheon Airport Terminal 1 bus timetable and operator directory if you need company details.
- Identify the operator responsible for your route.
- Check that company’s latest baggage rules and contact information.
For reference, routes 6001 and 6015 appear under Airport Limousine Co., while route 6701 appears under K Airport Limousine.
If you are boarding at a Seoul city stop instead of Incheon Airport, also check the direction of travel and whether that particular stop allows boarding.

Boarding the Airport Limousine Bus With Large Suitcases
Many airport limousine buses store large suitcases in compartments beneath the passenger seating area.
Staff or the driver may arrange the luggage according to the bus route and passengers’ destinations.
Before handing over your suitcase:
- Keep your passport, wallet, essential medication, and important valuables with you.
- Check that your suitcase is fully closed.
- Attach a luggage identification tag if appropriate.
- Tell the driver whether you are traveling to Incheon Airport Terminal 1 or Terminal 2 when asked.
- Keep any baggage identification slip issued by the operator.
- Check that you collect your own suitcase at the destination.
Do not place a large suitcase in the aisle or an emergency exit area. Follow the driver’s instructions about where luggage can be stored.
When going from Seoul to the airport, confirm your departure terminal before boarding. Airlines do not all use the same terminal.
Useful Korean Phrases for Extra Luggage
If you need to ask a driver or ticket counter employee about large or additional luggage, these simple Korean phrases may help.
Can I bring two suitcases?
캐리어 두 개 실을 수 있나요?
Is there an extra baggage fee?
추가 수하물 요금이 있나요?
Is this suitcase too large?
이 캐리어는 너무 큰가요?
Can I load this 28-inch suitcase?
28인치 캐리어도 실을 수 있나요?
I’m getting off at Terminal 1.
제1터미널에서 내려요.
When asking about an unusually large suitcase, showing the bag or its actual measurements can be more helpful than mentioning only the nominal inch size.
Frequently Asked Questions
Can I Take Two 28-Inch Suitcases on an Incheon Airport Limousine Bus?
Do not assume that two 28-inch suitcases will be accepted for one passenger. Incheon Airport’s general guidance places 28–32-inch suitcases in a one-piece category, while individual operators have their own size and weight conditions.
Check the operating company’s current policy before travel.
Can I Pay Extra to Bring a Third Suitcase?
Some operators publish additional baggage fees. However, paying extra does not automatically mean that a third suitcase will be accepted.
Actual dimensions, weight, storage capacity, and the company’s safety rules can affect acceptance.
Does a Backpack Count Toward the Luggage Allowance?
It may. Airport Limousine Co. specifically includes carried baggage in its published baggage count.
Smaller personal items and cabin baggage rules can differ between operators, so check your bus company’s conditions rather than assuming every backpack is excluded.
Is the Luggage Allowance the Same for Every Incheon Airport Bus?
No. Different operators can apply different baggage limits, dimensional rules, and extra charges.
The published guidance from Incheon Airport is useful for initial planning, but your specific operator’s terms and current instructions should determine what you can bring.
Final Checklist Before Your Airport Transfer
An Incheon Airport limousine bus can be a convenient way to travel between the airport and Seoul, but luggage rules deserve extra attention when you are carrying several large suitcases.
Before leaving your hotel, confirm four things:
- Your bus number and operating company.
- The number and individual weight of your bags.
- The actual outside dimensions of each large suitcase.
- Any additional fee or special permission required for excess luggage.
The most important rule is not to treat the airport’s general baggage guide as a guarantee for every bus. Check the operator’s own published conditions, particularly when traveling with a 28-inch or larger suitcase.
Last checked: October 10, 2026. Baggage allowances, fees, and operating conditions can change. When published documents differ, confirm the applicable rule with the company operating your exact route.
