Has anyone ever had problems buying flight tickets through Expedia? We've been looking at US flights, usually we book directly with Delta and their prices have been competitive but for this trip there's a huge difference, £620 cf £1014 and I'm trying to see the reason. We have booked through Expedia before but it was a long time ago. I'm getting a similar price on all the mainstream websites, Ebookers , Opodo etc..
Sometimes the difference is down to unpopular flight times - compare Expedias times with the airlines and see if they fit your needs. I have booked flights with them and had no issues but I often go direct with the airline to get more sociable flight times.
