They do clickbait at 40% off to go to their website and don't respect the price
I found cheap flights through Skyscanner that Trip.com was offering. Once in Trip.com they had several flights with Air France and KLM at about a 60% of the average price of other airlines for a flight from New Delhi, India to Puerto Vallarta, México. They made me click and go through the buying process to later tell me "The airline has changed their prices and policies" and asked me to buy at a way higher price. I refreshed and in their page they still had the cheaper fake options.
