I booked a return flight to the Republic of Ireland that has a layover in London Heathrow. I just learned that I need to get a standard visa for the UK just for this layover as I am from China. This is not possible given the time available. I have the option to rebook the flights through Paris and Geneva. Can anyone confirm that these airports do not require an airside transit visa for Chinese citizens?
What other European countries can I try to use instead of the UK for layovers in the future?
