OneTravel Customer Reviews

Good Service - to a point.  5
Flights were prompt, and aircraft staff were of usual standard. Seat assignments however, leave a lot to be desired. You ask us to contact you if you need anything special ..... the phone is NOT answered, so therefore seat assignment is not available at all, unless you are prepared to pay for it. It is not the way to travel for people on fixed incomes.
