I had the same problem some had with Onetravel.com: I've seen nowhere "seat assignment" was a paying service!
Just got curious weeks after I paid for my flight tickets and bam!
Receive another ticket receipt with an extra 12dollars charged on it!!!
I don't wanna pay anything extra and don't even care for seat assignment!
I didn't tick that box where it is said "I agree I'm gonna charged on my CB" except for when I bought my flight at the price agreed so I think this is robbery to charge me again for a service I do not want and was not aware was a paying one!
Here is my conf number # 13496981
Thank you for giving me my 12 bucks back or I'll never use the website again as well as encouraging people not to which is too bad for such a problem like that!
Thank you for your help!
