I recently booked and online trip via airfare.com. When a family tragedy occurred I had to change the date of my departure. As the ticket was non-cancellable and non-refundable I expected to pay a penalty for this action. I checked directly with the airlines (United and China Southern Airlines who were both wonderful to deal with) and they both said that an admin fee of $250 would take care of the problem. I felt that this was fair and was prepared to pay. The airlines recommended that we make the change through airfare.com since that was how we booked it. We tried for 5 days to contact airfare.com via phone, through their website and via email. After 5 days they finally responded and sent an "itinerary change form" that we had to sign and fax back. They agreed that when they received the form the change would be processed and we would be charged $250. Although annoyed that it took 5 days to get an answer I was satisfied with the result - until the next day. After Airfare.com received the form (and now only 2 days before my departure) they called to tell me that I needed to pay a $350 admin fee ($100 more than the airlines said they would charge) PLUS an airfare difference of over $1450. The total of my trip was now to be over $2300 ($890 for the original fare PLUS $1450 in new fees). When asked why they said that this is what the airlines were charging them. So...I went on to their very own website and fares with my same itinerary (with only a 2 day advance purchase) were only $950! Also, after talking with Airfare.com I called the airlines directly and they again reiterated that the only fee was a $250 admin change fee and there would be no difference in the fare. Ultimately China Southern airlines felt bad for me and cancelled the tickets through airfare.com and fixed my problem with a simple $250 change fee. I feel that airfare.com was extremely deceitful and dishonest. They are also VERY had to get hold of and will not return calls until threatened. DO NOT EVER book anything through Airfare.com. Use another online agency or go direct to the airlines.
