It’s about 12 years since I flew out of MIA and wasn’t expecting much, but apart from the nightmare of the roads to the airport all being worked on it is miles better than I remember with the mover rather than bus from car rental drop-off and the new location in the airport being big improvements. Glass of red before boarding...
By contrast, I was expecting Philadelphia to be a quietish and stood in line for immigration for over 1.5 hours

Hope you had a good flight.
