Is full name on booking required?
 

I just booked my first flight on BA to get to London for New Year's.

During the booking process it asked for "first name" and "last name" I simply inputted my first given name and last name. After the booking process was completed, on the manage my booking page it asks for advance passenger information in which I supplied all my given names on my passport (which includes my middle name).

This freaked me out a bit because I'm use to traveling on AA where it asks for your middle name and your entire name is put onto the ticket.

My question is should I have put all my given names in the "first name" box while booking? Will this create problems later on?

For example if my name is John William Henry Smith I simply just have "John Smith" on the booking and I supplied the rest in my advance passenger information.

I don't see why it should be a problem.

Last time I flew my full name wasn't on the ticket yet it was in the API.

As long as the first name and last name are correct and match the boarding pass and passport, it's fine.

I always travel with just my first and last names in my booking, whereas my passport has my middle name too.

no problem at all, i've not used my middle names in a booking for a long time

Same here. It shouldn't be a problem.
