I'm beginning to think I am jinxed. I've now changed the return online. Originally into Gatwick, then changed by BA to Heathrow, nothing done to make any changes since then until yesterday. An earlier flight on the same day was better for us and this was available in MMB so I changed to that online. Got a message on the screen saying "your flight is now confirmed" and "we've already sent a confirmation email". Only no email has been received and when I go into MMB I now have bookings for both flights (the one BA changed us to originally and the new flight chosen yesterday) under the same PNR and two e-ticket numbers per passenger according to the "print/email ticket receipt" option. Is this likely to sort itself out (I left it overnight just in case) or do I need to contact BA to sort it out?

Also if anyone has any thoughts about my last post that would be grand. Thanks.
