I think I've had 12 GUCs over the years and I've never had one go to the gate, let alone not clear -- all TATL. This is for the overwater leg though -- this past year I'm 1 for 3 on the domestic connection (and that 1 was LAX-SEA) with one to go tomorrow -- currently
#2 for 2 (was
#2 for 7 at OLCI) on LAX-JFK. I have no doubt there will be more SDCs and I will sit in the back.
Update: 12 hours out now #2 of 6 for 1 seat
