Thanks Steve

I didn't go into too much detail because I wasn't sure if it was the right place to. I booked online, at britishairways.com. I fly with BA a lot so am used to booking this way.

I'm going to Sweden in April, but flying into Gothenburg, and out of Stockholm. I booked the flight from London to Gothenburg quite a while ago. I then booked a flight from Stockholm to London for Wednesday April 11th. I KNOW this was the date I booked, as it's the day before my birthday, and I've got that week very well planned out! I made the booking late one night, and as I've said, I use the BA site quite frequently so am used to the system. So I booked, and as soon as I saw I had a confirmation email I was happy that the booking had been made - I only looked to see that the email was from BA, and didn't look any closer. So I was maybe a bit too trusting there - bookings have always been fine before so I had no reason to think this one might not be.

However, a few days later when sorting emails, I noticed that the title of the email said "7th March 2012" - this was when I started to worry. I thought maybe the error was just in the email title, so logged into my BA account, but saw that there, it was also booked for March 7th. I can see that this suggests user error, I really can, but it definitely wasn't. As I've said, I KNEW I was flying in April, and KNEW it was the 11th I was booking for. Also, I know I was on the right date when I made the booking, as I saw the alert "Only 1 seat(s) left at this price" - it's during Easter holidays, so flights are being booked up quickly. A midweek flight in March would not sell out nearly so fast. Also, I'm very computer literate so would not have made a mistake like that.

The flight in March is at the same time as the one I'd wished to book, in April, it's just five weeks wrong. So I can only presume that somehow the automatic booking system has just registered the right day, time and flight, but just got the wrong week.

I was told by the person I spoke to in customer services that if I'd called within 24 hours, the change could have been made free of charge, but as I was out of the 24 hour period, it would cost £30, plus about 600SEK, plus possible other charges - this is more than I paid for the flight in the first place. I'd be happy to pay these charges if I'd made a booking and then changed my mind, I understand that admin charges etc have to be in place. But this wasn't my error. Also, in the 24 hours after making the booking, there's absolutely no possibility that I'd have had the time to have spent over half an hour on the phone.

I've explained this over and over again in emails to and from the complaints department, but don't seem to be able to get anywhere. So currently, I'm booked onto a flight in one week's time which I will not be on. I'd have thought it would be in BA's interest to help me cancel the booking, to be able to re-sell the seat. I'm running out of ideas - what can I do?

Thanks
