Upgrade bumps?
 

What are the general rules for getting an unsolicited upgrade to F/C class? Does it happen when the coach is oversold and they need to free up space? I've gotten the upgrade bump a few of times in the past, once with no status at all, so just wondering..

Coach being oversold is the normal reason it would happen. If time is available, GA's would generally try to give the operational upgrade (op-up) to elites by status level.

If the GA doesn't have as much time, he or she might be more likely to give the upgrade to someone who hasn't boarded yet regardless of status, rather than deal with going down to the plane and moving people around.

sometimes you get lucky.....a very long shot would be a bump for weight & balance.....

One time I was flying LHR-SFO on BA, went to check in at the kiosk and found out I was bumped to business class (without a status). Guess sometimes it just happens behind the scenes..

i doubt that more than 1 in a thousand ft ers have been bumped from Y to C on a transatlantic.

Great, I've exhausted my chances for a free bump. :)

I was once bumped Y to C on a transpac. On an airline that I had 0 status with. Qantas, LAX-SYD. Flight was oversold, and I was one of the last to check in. Nice for the 14 hours!

It may be more common than you think. From 1999 to 2004 I was an engineer for a IBM partner, and did transatlantic trips at least once a month, often more. IBM policy was to fly AA whenever possible, so that's what the majority of my flights were. By the time I got status, I'd already been bumped from Y to C three or four times on transatlantic flights. At time I was in my early to mid twenties, and travelled in t-shirts and chinos - I never wore a suit. I almost always travelled alone, and on a full fare flexible economy ticket.
