I recently flew JFK-LHR-JFK and used E-SWUs (or so I thought) to upgrade both ways. I returned about a week ago. Agents at both ends had some difficulty pulling the upgrade, but seemed to be successful.

I called today to check my upgrade balance...and nothing had been pulled.

I'm assuming the system is updated in real time when they are pulled. Am I correct to assume that the agents didn't pull the E-SWUs and I got a free bump each way? If so, I'm not complaining.

Any thoughts would be appreciated.
