Was told the flight was overbooked so they selected only a few people to weight their bags and we were forced to check our luggage. We Once we got seated on the flight there were many seats vacant and our overhead bin was completely open. Both our luggage and our carryon were small. We had booked our tickets months in advance and we watched people carry two small suitcases on without one word to them. Am I upset?? Yes it was disappointing.

Busan airport overview

Travellers passing through Gimhae International Airport, located on the western end of Busan, South Korea, are in for a treat – the International Terminal was constructed in 2007, and is still virtually brand-spanking new.

But while the International Terminal is stylish and fresh, there is little in the way of entertainment or distractions – so perhaps take a good book or portable game.

What’s more there is a curfew in place that prevents planes taking off and landing between 11pm and 6am. This means that any passengers left stranded by a delayed flight or a long stopover aren’t able to grab a few hours shut-eye on an airport bench – everything shuts down after the last flight of the day.

Still, it’s a busy airport, with nearly seven million passengers coming in on flights to Gimhae International Airport each year from destinations such as Beijing, Tokyo, Hong Kong, Bangkok, Taipei, Vladivostok, Seoul, Guam and Munich.
