Nice work! I should have gone for more when I did a VDB recently. LAX-SYD was over-sold and my upgrade would not have come through so I asked for a VDB in exchange for a confirmed upgrade the following day without them taking another SWU as my stop was now longer than 12 hours. Maybe I should have got more? Any thoughts for next time I do this.
It's customary to get moved up one class of service gratis. The "another SWU" makes me wonder where you were coming from - if domestically, you might have been able to get that SWU exchanged to 500-milers. (Or, more likley, been issued a paper SWU to replace it)
That said, I fly the same route, and I'm pretty much always willing to help the GAs out with a rerouting, particularly since it typically adds only 20% or so - and usually less - to the travel time. Sans compensation. I'm not really inconvenienced, so what exactly am I being compensated for?
