Two stories from my "single" days...
on a SAS flight from copenhagen to SFO and I mentioned to this cute FA that I was hosting a party the following weekend. She asked for my number, and showed up the following Saturday with 6 FAs

She spend the next few years stopping in on me...
Coming back to SFO on CX, and spent the flight chatting up the FAs, got 6 numbers....
Lots of fun stories.
If you are (1) not stuck up, (2) reasonably attractive, and (3) in business/First, its not that hard....
Delta is not that bad, I just avoided this type of thing on United, never had any interest in people my mom's age.
