Not the greatest staff at gate desk, rather short spoken and no smiling facial expression!

Who sat in 18E? Because I’m pretty sure we are best friends for life.

Only issue was it was a morning flight and drink service had no coffee or hot tea available for some reason.

when paying for luggage on line it would be nice to have known that active military don’t pay for their luggage. We paid. When we checked in our luggage in San Diego they should have told us then too.
