Currently having trouble with Tour Company who claim BA have only just changed Barcelona flights to T3. I am pretty sure BCN has been a T3 service since at least Feb 2017. Have tried searching both FT and Google but cannot find any lists or references as to the dates when certain services are switched between Terminals. Are there any people in the know who can point me in the right direction please and more specifically when BCN flights started operating from T3?

Same Tour Operator was showing Denver flights from T5 and I know these have been T3 since at least 2015.

I have a good 'BS' detection system but being able to go back to them with specific dates to disprove their statements would be really useful. Really annoys me when the 'BSE - Blame Somebody Else' excuse is used incorrectly.

TIA
