I just returned from a 4 day trip to Orlando with my husband and son (15). We were able to upgrade each way to business class. I have not figured out why more people are not doing this. Air Tran is the only airline I know of that has a resonable fee to upgrade. For me space is the issue. I hate being crammed into those small seats.

The plane from BWI to MCO was equipped with XM. The quality was great and I did not notice any change in volume with the announcements. My son even saved his IPOD battery and listened to XM for a while.

We have driven to Orlando a couple of times for longer vacations and I must say it was nice to fly for a change. MCO is a great airport with lots of restaurants and a Hyatt right there.
