Seattle Reviews

One Travel is the only way to plan a trip  5

I have dealt with a lot of online travel companies and have often had trouble with the bookings or the service was not rated correctly when it comes to hotels and cars. That being said, OneTravel gave me the best deals, delivered as promised, and both the airline and rental car reservations were confirmed and delivered as promised. Great service and communication. Very pleased and will use OneTravel for all future trips.
