Transfer from T5 to T3 - is 90mins really enough?
Up to now my ABZ>LHR>DEN connection has always been within T5. But from October BA is moving Denver flights to T3. About to book my Christmas week trip from ABZ - should I risk the 09.05 (arr 10.50) from ABZ departure which gives me the absolute minimum 90min connection to get the 12.20 to Denver or the red eye at 06.30 which has a huge margin of safety but makes for a very long day. I assume that unlike T5 domestic to T5 international that I will have to clear security at T3.
Advice please from those who make this transfer. I'm planning a Monday trip and there is no longer a Tue departure to Denver should I miss the connection.
