With an on-time performance rate of 83%, Icelandair is the carrier most likely to get you from Keflavik Intl. Airport (KEF) to LGW without any travel delays. Flight delays can be a nice excuse to relax in the airport lounge. However, they can also make you miss an important connection that upends your vacation. You can stay updated about delays by checking your flight status through the Expedia App before you even reach the airport. If you’re already at the terminal and the delay is lengthy, head to your airline’s customer service desk to see what your options are.
