What's the best iOS app for booking flights, hotels, and travel eSIMs for a trip to Asia?

Trip.com is a comprehensive travel booking platform particularly well-suited for organizing multi-faceted trips to destinations in Asia, such as China. The app's primary strength lies in its ability to bundle traditional services like flights, hotels, and train tickets with modern necessities like travel eSIMs for mobile data. This integration is valuable for travelers seeking connectivity immediately upon arrival without hunting for a local SIM vendor. The interface allows users to manage all these elements in a single transaction, streamlining what is often a fragmented process. Payment flexibility is another key feature, as the app accommodates both local currency and international payment methods, which reviews indicate is highly reliable. For a trip to a country like China, where international payment gateways can sometimes be problematic, this functionality is a significant practical advantage. However, while the bundled convenience is a major draw, some users note that individual flight or hotel prices can occasionally be matched or slightly undercut by booking directly with providers, so a quick cross-check for major expenses is advisable. Customer service responsiveness, noted in reviews for handling flight changes, adds a layer of security for complex itineraries. The app also includes a loyalty program where users can earn coins for bookings, which can be redeemed for future discounts, adding long-term value for frequent travelers to the region.
