I would not stress out about UAL. The media is making a really big deal out of it. There is always one airline in the news that is sensationalized. Just this week I bought a $2,000 ticket to Bangkok, Thailand on UAL for the week of 4th July. If I truly believed that the airline was going to cease all operations I would not have chunked down that kind of non-refundable cash. Before UAL was in the news it was US Air then before that it was Delta. Sure there are some issues but it is never as bad as the media makes it out to be IMHO. Relax you will get to WDW just fine.
