Thank you all!
It will be my 4th trip to MCO, only one of them for vacation.
Via CLT and PHL and in March directly to MCO.
Knowing the FT trick not to recheck the luggage for delivery at the main terminal, my MCO experience was not too bad. For surfe better than my PHL experience.
Obviously, this could be due to my small sample size (despite being BAEC Gold for about 5 years.[1]
No issues with Aer Lingus. But only flown between DUB and Germany, never to travel overseas.

Anyway, thanks again for the kind help.

[1] but only until the end of November this year. Then ‚Double Silver‘ : enough TP for silver & downgrade to silver.
