Sorry to tie up a thread but I can't get PMs to work and time is a factor.
BT11, I know you're planning a trip to NYC for March. Noticed today that USAirways has reduced airfare until Mid-March. The catch is that flights need to be booked by midnight tonight.
Depending on which city and day of week you depart the fare can goes as low as $118. Increases to $138 for travel on a Friday. These are excellent prices and the lowest I've seen in ages.
Don't know if your dad has booked the flights yet, but I don't think you'll find any better deals. Like I said though, it needs to be booked tonight. Use their website usairways.com.
Rest in peace, Iflitifloat.
