Traveloka is the best travel booking site that I can recommend leave no mention of the date change, cancellation or refund. In my recent trip from Bangladesh to Thailand, there were no sudden charges because of their well-known prices. This app has an outstanding interface through which customers get to find better deals and handle their reservations in an easier way. I really love when customers can search, peruse through different airlines' costs and compare these rates against each other. They did a good job at booking and check-in process. I have been using Traveloka for several years already without facing any challenges at all. Just give it a try and you will be amazed at what this travel agency application can do!
