Earlier this month McGregor, nicknamed 'The Notorious', was named as Betsafe's new ambassador.
The competition winners, who will be joined on-board by boxer Tony Bellew and UFC fighter Jimi Manuwa, have also been give tickets to Saturday's fight against Mayweather.
As part of the stunt, McGregor featured in a pre-flight safety video (below) to ensure passengers adhere to the airline's mock rules and regulations.
McGregor says in the clip: "Welcome to Notorious Airways, this is your captain speaking, and until the seat belt sign goes off, you'll do f*cking nothing. Buckle up, it's going to be a bumpy ride, but not as bumpy as the amount of bumps Floyd's going to get in the mouth.
"Thank you for flying with Notorious Airways, we appreciate your support and remember, we're not here to take part, we're here to take over."
It is understood Betsafe appointed PR firm Pretty Green to create the campaign. The agency declined to comment.
