Back in June of 2024, we scheduled our return flight from Phuket, Thailand to Phoenix, Arizona on February 15,2025 through Arangrant. All seemed fine until Arangrant totally dropped the ball on February 9,2025 with a change of flights email. Our original flight schedule returned us via Cathay Pacific from Phuket to Hong Kong and Hong Kong to San Francisco, then connecting on American Airlines from San Francisco to Phoenix, Arizona. We were advised on that date via email that our flight home had been cancelled. We were given two options: one, to cancel our flights entirely with potential refund, stranding us in Thailand to make our own way home, or two, accept immediately via return email a reroute through Los Angeles adding 13 overnight layover hours and a total travel time in excess of 36 hours versus an original 23 hour time. We initially opted for not being stranded only to find out later that the only issue was with American Airlines, the final segment of our trip. After not hearing anything in the way of confirmation from Arangrant, we received a check-in email from Cathay Pacific on Thursday 2/13/2025 which showed us on our original flights to San Francisco. That day we requested via email that our original tickets be honored, and we would terminate the travel in San Francisco to find our own way back to Phoenix. We went to the airport on Feb 15,2025 believing we were checked in on our original tickets, only to be told that Arangrant had sent e-ticket changes in the middle of the night to the Los Angeles flights. Our attempts at contacting Arangrant prior to our flights resulted in us being put on hold and then dropped with less than an hour before flight time. Needing to get through security and to the gate, we confirmed through Cathay Pacific that we could get this all corrected in Hong Kong since both the original tickets and the "substitutes" had us on the Phuket to Hong Kong flight. Upon arrival in Hong Kong, and having no update, confirmation, or change information from Arangrant, we proceeded to arrange through Cathay Pacific our continuation flight to San Francisco. Arangrant left us no option but to try handling this on our own so that we could safely make it back to the US in a timely fashion. We attempted to follow Arangrant's written guidance by requesting our ticketing be reverted back to our original flights per their minimum 24 hour prior notice - Thursday versus a Saturday flight, but we had no response from them. Our attempts at reasonably correcting this massive failure to communicate with us prior to the flights with a reimbursement for the unused portion of our tickets from San Francisco (or Los Angeles) to Phoenix have been met with an arrogance and total lack of willingness to find a reasonable solution. As a supposedly caring service industry entity, they have steadfastly rejected all aspects of reasonable dealings. Their initial and only "offer" was a $50 voucher to be used for future services with their company. Rest assured, that for all the extensive traveling we do (this one was the return segment of a 46-day excursion to the far east), there is no way that we would ever use this company again. Although we have experienced flight delays, travel itinerary changes, booking issues and flight cancellations on previous travels, this is the first time we have been subjected to such unhelpful misrepresentation, lack of communication and refusal to acknowledge any responsibility for mishandling the issues encountered.
