Thanks. The creditcard company will only re-imburse me for the actual ticket price, so if I have a problem say 2 weeks before departure, replacement tickets are going to be a lot more expensive to get to PVR from DEN.
Another small problem is that the ticket sold by AA gives me a 45 min connection time in DFW, is that feasible? Perhaps the wrong forum to ask this, but not to worry, I am not a passenger or plane spotter but a commercial pilot with a foggy memory of DFW. I could probably get a pass, but don't want to risk getting bumped in the summer.
