Schengen Entry....or No?
I have a similar question, I will travelling with my girlfriend who holds a Thai Passport with a multiple entry Schengen visa. Current I have a award ticket back to BKK as following: ZRH-ARN-BKK. I might change the flight ZRH-LON-BKK. For UK its required a separate visa, if we stay only in transit does it work without UK visa?
