I haven't flown them but I did get a coupon from one of the Las Vegas hotels for 20% off on air for National. I think it was Caesar's Palace but I'm not sure. I have it at home. I'll take a look at it tonight and see who sent it. For some reason I'm thinking the hotel had a share in ownership of the airline or something like that. Well, a little competition never did anyone any harm. Who knows? They may offer some good fares.
