When making travel plans DO NOT use priceline.com. I tried to change a flight and checked the fares before I did, to make sure then hadn't skyrocketed. Fortunately they were only $50 more on the same airline. They tell me that to change two tickets it would cost $2,900! That includes a $200 per ticket change fee from the airline, $30 per ticket "processing fee", leaving a fare difference on each ticket at 1,220? The flight on their site remains $949, even after being refreshed as I speak to them on the phone. They couldn't explain to me how they got that number. I've been on hold after asking for a supervisor for an hour now. Priceline.com are thieves. And of course the airline can't help me because they can't change tickets that were issued by priceline. Great, business practices priceline. From now on I will use them to search for flights then go to the airline directly to buy my ticket.
