Anecdotal: I was at FLL last Sat. The southwest ticket counter had a few people and I waited on two arriving flights that both were relatively empty. The Alaska flight my friend was in was buzzing and had about 30 people checking in.
i hung out on a deserted upper deck of the parking garage. There were a few planes around but mostly quiet. I had been to FLL just after the pandemic started and the day before the Canadian border closed. Other then the rush of people trying to get back to Canada, the airport was more deserted then than now, but not significantly. The industry has right sized well. Traffic is going up. Flights are going out with 10-20 people instead of 1-2 but there are also fewer flights. we’re not looking at any significant uptick but yes, there is light and hope for the future
