I am trying to book an award ticket on BA, and when it asks for passenger information, it asks for only first and last name, but on my passport, I have a middle initial as well. Other airlines usually ask for a middle initial and ticket the name as FIRSTM LAST. For my BA award ticket, should I just leave out my middle initial, or should I attach it at the end of my first name, or do FIRST M? I am traveling between US and Hong Kong.
