GMP Seoul

How deep the GMP board really is

The table above says where a courier can fly from GMP. This reads the same 19 destinations back for the questions a dispatcher asks second: how much of the board rests on one airline, how much of it runs less than daily, whether the return leg is as thick as the outbound, what the clock here does to a Gulf working day and which of the destinations shut at night, all of it computed on 2026-09-07 from AeroDataBox scheduled route statistics.

• 7of the 19 destinations are flown by one airline
• 4destinations run less than once a day
• 6destinations have four or more departures a day
• 42.1%of the destinations name Asiana Airlines, the largest presence here

Who holds the departures at GMP

24 airlines appear on the GMP board and they do not hold it evenly. Asiana Airlines is on 8 of the 19 destinations, 42.1 per cent of them, and on 1 of those it is the only airline flying the sector. The destinations it appears on carry 164 of the 205.7 departures a day this airport files, though other airlines fly some of the same sectors, so read that as reach rather than as a share of the aircraft.

The next largest presence is Korean Air on 8 destinations. 15 of the 24 airlines at GMP appear on a single destination each, which is the long tail every airport carries, and none of it is a rebooking option when the sector you need is the one that fell over.

That is a middling concentration at GMP: one airline on 42.1 per cent of the destinations and the other 57.9 per cent spread across 23 airlines. A cancellation inside the Asiana Airlines network is often survivable inside the same booking, but on the 11 destinations Asiana Airlines does not touch, a rebooking means moving to a carrier the desk has to check for a through fare first.

How much of the GMP board is daily

Of the 19 destinations, 15 are flown at least once a day and 4 are not, 4 of them running once a week or less. The median destination on the GMP board is flown about twice a day.

An average of 0.14 flights a day is the schedule statistic, and it is worth translating it before anything is promised to anybody: GMP to Tokyo (NRT) is about one a week, so a missed departure there is not a delay of hours, it is the next slot.

The five busiest destinations carry 179.4 of the 205.7 departures a day, 87.2 per cent of the whole board. On that arithmetic GMP is five sectors and a short tail, so the depth on the board above is thinner than the destination count suggests and a hand carry that is not going to one of those five is planned around a single departure time.

The four destinations out of GMP where one airline holds the sector and files fewer than seven departures a week, with the weekly figure taken as the average daily rate multiplied by seven rather than as a fixed timetable.

The way back from GMP

The desk holds the return direction for 11 of the 19 destinations, and a courier plans the way back on those figures rather than on the outbound. On none of those 11 does the return run more than a quarter thinner than the outbound, so a turnaround through GMP is a question of hours rather than of whether an aircraft exists.

It runs the other way as well: Tokoname (NGO) files 3.4 a day back into GMP against 2.3 outbound, which is the shape that strands a courier at this end rather than at the far end.

The clock at GMP

GMP keeps Asia/Seoul time, five hours ahead of Dubai all year.

When it is 09:00 on a Dubai working morning it is 14:00 at GMP, so a nine to six day at each end overlaps for four hours. A customs question raised in the last five hours of the Dubai afternoon reaches nobody at GMP until the next morning, which is the practical limit on a same day instruction here.

The night at GMP

2 of the destinations from here carry a documented night restriction of their own, which is a departure time question at this end rather than an arrival problem at the other.

Into Geneva (GVA) the door shuts at 00:00 local, so the last departure from GMP that lands inside it leaves around 19:41, on a modelled block of 11h 19m. Into Tokyo (NRT) the door shuts at 23:00 local, so the last departure from GMP that lands inside it leaves around 20:56, on a modelled block of 2h 04m. Those two departure times out of GMP are worked backwards from the published window with the block time model this site uses everywhere, 720 to 880 km an hour by sector length with thirty minutes on the ground, so they are arithmetic rather than a timetable and the desk checks the published departure before it promises the landing.

Where GMP turns up on the rest of this site

The airport also sits behind the South Korea country desk, which sets out the customs practice, the working week and the road legs behind this airport.

Twelve courier postings name GMP as the airport a courier here flies from: Incheon, Suwon and Cheongju-si.

To price a movement rather than read the board, the route calculator opens with GMP already set as the origin, and it works out the flying time, the distance and the delivery hour for any of the 19 destinations above.
