Good Dialog Folks.
In general, I think my concept is greedy, and because I do love SWA, my free ticket run is out. I just got excited last week when we traveled together and were offered $900 to sit at the airport for 4 hours (didn't happen).
That said, my conscience is clear by fully intending to travel but booking a flight that is almost full, with the intention of accepting an offer should I get bumped. My wife and I average 60 RT flights with WN per year, and our "strength of schedule" varies. Sometimes we can take the bump, sometimes we can't.
I'll just keep an eye on flight prices and such. I haven't heard anything that would clue-me-in on specific flights/routes to take or other methods for pinpointing which flights are full.
