KAYAK’s top tips for finding a cheap flight from London to Seoul Gimpo Intl Airport

  • London is the biggest travel hub in the UK, with six international airports servicing the city and the south-east region, such as London City Airport (LCY), Heathrow (LHR), Gatwick (LGW), Luton (LTN), Stansted (STN) and Southend (SEN). London City Airport is the closest to Central London and a great option for those who want quick access to the airport. Gatwick, Luton and Stansted are hubs for low-cost airlines like easyJet and Ryanair, whereas Heathrow is a hub for British Airways and the main airport for long-distance international travel.
  • Seoul (SEL) is served by two main international airports: Incheon International airport (ICN), 30 miles from the city centre, and Gimpo International Airport (GMP), about 9 miles from downtown Seoul. Incheon International airport is the main hub for international flights from Europe and the Americas, with Gimpo airport servicing domestic flights and flights to other South-East Asian destinations.

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.
