I just spoke to a friend of mine who works for BA on the help desk side of things.

She has just told me the amount of calls they get from customers who are stuck and are trying to check in with a ticket that is not correct dated is unreal.

The problem is when they operator is taking you call it is very easy to not close the drop down menu for the month correctly and this is how it gives the wrong date.

She reccomends you take a friendly approach and back it up with all the other things you have done for this this trip and ask why would you make the tickets a different date. Do it soon otherwise it will be deemed as a genuine mistake on your part.

They sure dont like to loose any customers at the moment and it is worth mentioning how much you do spend with them.She reccomends you dont ramm it down their throats or threaten to remove your business as this is what they hear all day long.
