Trip.com is considered a trusted travel website, but it's not currently one of the best. It's owned by the same company as Skyscanner, which adds to its credibility as Skyscanner is ranked one of the best travel websites.
We were able to find lots of negative user reviews of the site, ranging from 1.2 stars to 3.9 stars on sites like SiteJabber and TrustPilot. The Apple App Store reviews average 4.7 stars, however, with 4.5 stars on the Google Play Store.
There are better sites around to use for pricing and booking hotels, flights, rental cars, and attractions - Skyscanner and Booking.com specifically - but Trip.com is legitimate.
