The line to enter the terminal in Florida Terminal #2 (on Dec 18) extended from the entry doors to the other end of the building & back again (double line for people with & without medallions). I couldn't actually see the end of the line. When the doors opened it didn't make any difference which line you were in outside the terminal as both lines merged together in the building. Lots of large families.
By the time we reached the Elite/Suite lounge it was packed, although boarding was called rather quickly.
So much for an Elite priority line.
