機票姓同名反轉左

Yes, it is no problem. 因為在online booking (包括我在內), 經常有人會將surname 和 first name 調轉.

For example, Wong is surname, Tai-Man is first name

Tai Man Wong (Original Name)
Wong Tai Man (Ok for Airline)
Wong Man Tai (Unacceptable)

我在德國airline (LH) online booking, 將名同姓調轉, 我check過德國airline Hong Kong reservation office, My friends working in Travel agent and 做airline 地勤的friend 都無問題, 我順利上機.

Don't worry la! Have a nice trip!

只有出境才check ticket, 入境主要check passport, visa, 和入境紙
