Frequently asked questions

Is it cheaper to buy a plane ticket from Houston Airport to Ulsan Airport (USN) last minute?
Booking your flight from George Bush Intercontinental Airport (IAH) to USN at the last minute could save you a pretty penny if you're lucky enough to find a terrific deal. However, tickets usually don't drop in price as the departure date nears. If you choose to wait, flights could also be sold out or the best seats taken (we hope you like the middle seat!). If you want to be on the safe side, book well ahead of your departure date. Remember that some of the most awesome deals can be found up to a year in advance. If your favorite airline hasn't released tickets yet, check back regularly as deals are constantly updated on Expedia.
