For all airlines check Tues/Wed at midnight.. They usually do competition drops for those that look for deals
This is good info from VPchill... I want to add that you should
always check airfair on Monday morning because the Airlines distribute out a certain amount of seat inventory for travel sites (orbits, travelocity,priceline,etc.) to sell through out the week, and as the flight sells seats the price goes up. Most of these travel sites then return all unbooked flight inventory back to the airline at the weeks end (usually Sunday night/Monday morning) between 12am-7am eastern (usually done electronicaly too) creating alot of inventory for the airlines. The airlines then usually drop price and redistribute over Mon/Tues/Weds. I found that
www.kayak.com and
www.travelocity.com are usually been the best priced on Monday. Using kayak is a way to search multiple airlines at once, it is an airline search engin, it show you all the options for different airlines then link you to the airline directly to book the flight. This applies to any flights any where, not just to POP. Good Luck.
