OneTravel has excellent prices, but if you have to cancel or change your itinerary, you can kiss your money goodbye. I bought a round-trip ticket for an excellent price. However, the cancellation fee was the same amount as the cost of the ticket. The change fee was not so bad, and everyone has to pay the difference in cost, but OneTravel has a requirement that you first have to buy another ticket (at a horrible price), before you can apply what is left of your credit. In other words, the credit was useless. I never took the trip. The money I spent was lost, completely. I don't recommend using this company, UNLESS you are 100% certain that you will not change any part of your booking. So, OneTravel has great prices, but if you need to make changes, their fees and penalties and policies will make you wish you had never heard of this company.
FROM ONE TRAVEL: we appreciate you feedback and are sorry you feel this way. Please be advised that we are bonded by the airlines terms and conditions and yes, sometimes to pay a difference ends up being higher than what the ticket cost but its due to the fare inventory available at the moment and the change fee.
RESPONSE: Today your company denied ever hearing of the Airline for which I bought tickets. I bought the tickets on this airline from YOUR company. The airline is GOL in Brasil. Your company sold me GOL tickets, and then claimed to never have heard of the airline. This is a bad faith business practice. Your company also refused to accept a flight on GOL that I found on my own for about FIVE HUNDRED dollars less. I lost all of the money that I spent with your company. There is no excuse for what your company did in this instance, and there are over 150 complaints about OneTravel on consumeraffairs.com, and tons of complaints on other websites as well.
