Has anybody recently tried an immediate turnround on the BA LHR-KRT route? If so, I'd be very interested in knowing about your experiences! Is a visa necessary if one is just flying in and out again within 2-3 hours of arrival? If so, can it be bought at KRT or must it be obtained in advance of the trip? Would BA deny check-in without a visa in your passport? There are some fairly discouraging reports about the KRT airport. Is it really as bad as some say? I searched for answers to these questions in the archive but couldn't find anything. LHR-KRT-LHR is clearly a rewarding mileage run on an xONEx but do the potential hassles associated with getting in & out of KRT outweigh the (mileage) benefits? I have an xONEx reservation on hold but have not yet ticketed.
