If there was 0 star I would give it. If you value time and energy during your vacation,never use this platform. I had to book a flight in South America because the airline website and app wouldn't allow my credit card to process Long story short. Original domestic flight booking in Ecuador had 1pc hand carry and 1 pc 23kg checkin baggage incl, and this was valid both ways outbound and inbound. As I was traveling with additional luggage for a long trip from Asia,I purchased an additional 23kg check in both ways. I also purchased all the extras on trip.com like platinum service etc etc. Unfortunately the airline canceled the outbound flight and I had to change it to another date, but I never changed any details regarding the inbound. On the first leg on arrival, the airline informed me that I had 2 checked bags allowance in the way out but only 1 on the inbound. To my horror, when I checked the reissued ticket (after the outbound change) trip.com had removed the original free baggage allowance. I spent countless hours on chat and email with a completely unhelpful bunch of incompetent agents, none of whom could explain how or why this had happened. Eventually they offered my compensation of usd28, which as yet, is still pending. Whether this was a technical issue with ticket issuance, or whether it was a human error, or whether it was the airline (not so as I just completed the inbound flight and none of the airline counter staff could explain it....I have the original ticket printed with the free allowance included...) or whether this is some ploy for trip.com to earn additional revenue by cheating customers....remains a mystery as NO EXPLANATION WAS OFFERED AT ALL BY ANY OF THE MANY MANY AGENTS I CHATTED AND EMAILED WITH OVER THE LAST 8 DAYS.... If you want to avoid hassle, just get a local travel agency to book your reservations in exotic destinations. DO NOT TRUST TRIP.COM EVER!!!!!
