Stay away from this booking platform! Prices might look more reasonable but if you run in to issues they are a complete nightmare. My sister and I took my mom on a 70th birthday trip. Purchased our seats and baggage ahead of time through trip.com. Went to check in for our flight and the seats and baggage were not showing. Called trip.com kept getting the run around, no clear solution. Was told due to time to repurchase and they would refund. Two weeks later, still no refund. I have received 7 emails saying they are looking in to it. I have spoken to someone multiple times, uploaded receipts only to be told they are looking in to it. Waiting on almost 400 dollars to be reimbursed. I am still confused on what further needs to be looked in to when receipts of the original purchase are uploaded, plus the repurchase which they directed, and now two weeks and no refund as of yet. Again, DO NOT USE this platform. Extremely poor customer service. Not worth the cheaper ticket.
