Would give less than zero if I could. They lied to us, said that our flight tickets, which were cancelled due to COVID, could not be refunded because the airline was only issuing credit vouchers, and we MUST rebook using AirTreks. Just spent 4 hours on hold before speaking to the airline itself, they said they had issued a FULL REFUND to Air Treks last May 25th, 2021. Even when we had tried to rebook, they wanted to charge us DOUBLE what the currently posted air fare cost was on the airline they were quoting, claiming that the "fares have increased" since the original booking that was cancelled (never mind that this was a different flight, and I sent them a screenshot of the actual current pricing to show their lies).
UPDATE: April 6th, 2022--still waiting for AirTreks to do the right thing--emailed back and forth with multiple staff including Florencia and Maria, who state that their policies aren't the same as the airlines, even though their policies say refunds aren't possible in the case of "non-refundable tickets" from the airlines--but in fact these tickets WERE fully refunded to them by the airline last summer, and Air Treks could have sent that refund back to me. Florencia ignored this fact and got indignant that I "threatened" them with the Better Business Bureau because I filed a complaint with the BBB two weeks ago. Of course, AirTreks has NOT responded to the BBB. This company DOES NOT care about anything except keeping your money. RUN FAR AWAY FROM THESE PEOPLE!!!
