Took a one stop flight SFO to San Jose Costa Rica, via Houston. The first flight was jammed and I was asked to check my carry-on as I was boarding in group 4 and my wife was in group 2. They took it at the gate and lucky for us took the baggage tag off in the jet way which was nice as I was boarding a boat in Costa Rica and it for some reason things went wrong, I would be on the ocean with no bags. Indeed one of the passengers did get her carry-on lost which was a bummer as it had some important stuff in it. They were offering up to $700 for volunteers but none came forward. I had to have my bag put in the very back of the plane when I was only in row 12 so waited until it emptied before being able to exit. A minor irritation though. At least there was in seat entertainment even though I had many movies downloaded onto my iPad. No other hiccups, easy otherwise. I have been flying United for 30 years but frequent flyer miles are almost worthless these days. Lucky my wife is still earning miles as a consultant.
