Flew into Kos by easyJet from LGW on Thurs 2 June, 5 minute Q at bag drop, 5 minute Q at security left LGW about 40 mins late. Arrived Kos about 22.30. Short queue for passports to be stamped. No health check or request to see Covid jab evidence; 5 or 10 minute wait for suitcase to arrive on carousel, walked out of terminal, 10 minute wait for taxi. We were in Kos town about 1.5 hours after wheels hit the runway.
Return to Gatwick flight on Sat 11th June around 22.00 from Kos. Short 10 min check-in/bag drop Q. About 2 minute queue for security. Plane departed around 1/2 hour late. Arrived LGW approx. 00.15. No queue for passport machines, bags in baggage hall half hour after wheels hit the stand.
