SO we NEVER fly.....simply because it is just WAY too expensive for us and I really prefer to drive! BUT on our upcoming surprise trip I am looking at flying because of time restraints. And I have a couple of questions that might be dumb! 1. Does air fare go up as the travel date gets closer? 2. Do they ever add flights at a busy time (like Christmas) near the travel date? 3. If I book a flight and something changes can I get a refund or change the flight ...say from Christmas to summer?? Thank you so much for your help!
