Hello, I am off on a trip to the US next week. My ticket lists me as 'Mr Scrutton Street', but my ESTA has my full name with my middle name - so 'Mr Scrutton George Street.' (the latter is what is in my passport.)

Is this going to present a problem that will prevent me checking in online.? Should I call BA to amend the ticket to use my full name? I tend never to put my middle name in a booking for the sake of simplicity, but now wondering whether the need to make it identical to the ESTA trumps that?
