question about online book[ing]
Hi, I try to book a ticket for me and my wife, I find there are only two low price tickets left.I plan to buy them.After I input our personal information and before we pay for it, I go back to prevous pages to double-check our information, however, when I come back I find the seat we choose are occupied and the price is gone.I guess the system may think someone hold the reservation(I and my wife), therefore we can't continue! am I right?or someone happens to buy the tickets at the same time and same seat?If I am right, how long I have to wait for the price come back (I mean the system release the holding).anyone have same experience?
Thanks
