I actually worked at a call center for Priceline - 7 years ago- but still. I was in the "air travel service dept" A. You don't get to pick your times / airlines. you can arrive at 7 am or midnight! B. you can't change or cancel it. You get what you get. Period. C. If the airlines change their schedule, a lot of times they wont help you since you booked thru Priceline. You have to call Priceline. D. They can give you diff airlines w a layover. Ex. You fly delta to pittsburgh and then you fly united to Orlando. It just makes it tricky if a flights delayed or there is a change in schedule. E. I've also heard of people not having enough time on layovers. Like a half hour. Which will make some ppl panic! Or again could be a problem if a flights delayed. All I am saying is you better be VERY careful when using Priceline Name your own price. I am certain some ppl have had positive experiences. Obviously only ppl w problems would call! Know what your getting into and understand the conditions! Things could have changed since I have been there. Check and double check you put the info in right! If you put the wrong airport, your toast! I don't use it myself, But I can get a direct flight for $100! It might be worth it if you live far and tickets are $$$$. Just use EXTREME caution.
