The airline schedules are available up to early July 2009. For those of you who booked trips in the first half of 2009, did you go ahead and book your flight? On one hand, fares could well go up, so it could potentially save some money. On the other hand, it's a big chunk of money to part with when the trip is so far away. I'm going to buy trip insurance, so I'm not worried about losing the airfare if I book, but I'm still debating. Any thoughts?
