Prince Harry doesn't always get the royal treatment.
ET has learned that Harry, 33, and his 36-year-old fiancee, Meghan Markle, flew commercial to France, where they spent their New Year's holiday in Monaco and Monte Carlo.
It was a quick trip for the couple, whose first joint engagement of 2018 will take place next week in Brixton, London. Harry and Meghan will visit the studios of youth-orientated radio station Reprezent FM, located at POP Brixton.
Kate does have some personal ties to British Airways. Her mother, Carole Middleton, was reportedly once an employee of the airline, and served as a flight attendant when she met the Duchess' dad, Michael.
