Hi everyone
I booked a flight with an agent (getaflight uk) to LHR-KUL-HAN, and their site did not request a middle name, only 'First Name' and 'Surname', so I only entered my first name, not middle name. I have a middle name on my passport.

I've spoken to MH, they've told me my middle name needs to be on the booking for all international flights if it's on my passport, and I might be denied boarding if it's not on the ticket

I've spoken to the getaflight, they've asked my to pay £250 for a name correction if I want my middle name added to the booking, as I should have entered my middle name along with my first name in the 'first name' field.

Do I really need my middle name on the ticket, and as their booking form clearly only asks for first name and surname, not first names, what are my rights to get them to add my middle name without paying the name correction charge?

Thanks for any advice!
