Every 20–30 minutes, Airport Limousine 6702 rolls out of ICN
This 6702 bus is aimed squarely at southern Seoul hotel zones around Jamsil and the COEX area, running from both T1 and T2 at Incheon. Daytime frequency sits around every 20–30 minutes, and the ride runs about 70–90 minutes depending on Gangnam-side traffic. Fares land in the $14–16 range per person, higher than a regular city bus but cheaper than most taxis from ICN.
From Incheon T1 and T2, 6702 heads into Seoul on the expressway before looping through specific hotel clusters in the south. That hotel drop-off is the key feature: families on Reddit call it “much easier with kids and big bags” compared to switching from AREX to Line 2 at Seoul Station or Hongik. Expect the highway segment to feel comparable to other 67xx lines, with extra time added once you hit the COEX/Jamsil streets.
Seating on 6702 is closer to a deluxe coach than a city bus, with individual seats and luggage stored underneath or in a front rack; some riders report complimentary water bottles on certain runs, though you shouldn’t bank on it. Payment works with cash in KRW, major transit cards like T-money, and often credit card on board, but the safest bet is a T-money card topped up before you leave T1 or T2.
What regulars do: they compare 6702 against KAL Limousine lines that hit the same hotels in the COEX complex or Jamsil within a similar 70–90 minute window, then pick based on timetable and first/last bus times. Light-packers headed to COEX sometimes skip all buses and ride AREX from ICN to Seoul Station, then Line 2 to Samseong in about 60–75 minutes total, using 6702 only when rolling in with two or three checked bags.
Watch out for evening traffic: reviews call out brutal jams on the Gangnam side after 5 p.m., pushing that 70-minute ride closer to the 90-minute end or more. Service frequency also thins later at night, so waits can stretch past 30 minutes compared with the daytime 20–30 minute pattern. Build the buffer if you’re catching a late dinner or a 9 p.m. show around COEX.
One practical tip: before you queue at T1 or T2, pull up the exact 6702 stop list for your date and confirm your hotel name is printed there; if it isn’t, weigh KAL Limousine or AREX + subway rather than gambling on a nearby stop with heavy luggage.
