Momondo
Momondo is a metasearch platform owned by Booking.com that offers unique features for flight searches. It provides options to filter standard parameters such as airline, number of stops, and nearby airports, along with niche filters such as the type of aircraft, layover duration, and airline alliances. Similar to Kayak, Momondo allows users to sort fares by "cheapest" and "best." Additionally, it has introduced its own fares that can be booked directly on the website. The platform also offers price alerts and has useful bar graphs that display fare differences around selected dates.
Momondo offers opaque fares from "major airlines," which the site does not identify until after purchase. These fares are typically lower than openly advertised prices by individual airlines. Interestingly, Momondo also includes alternative transportation options like bus fares, providing an excellent point of comparison for those preferring air travel.
Although Momondo has its advantages, you should also keep in mind a few drawbacks. Firstly, the website almost always requires booking through a third-party travel site. Additionally, it may not be possible to calculate "complex" flights. If your goal is to earn credit card rewards points by booking directly with an airline, it would be more beneficial to use Google Flights or Kayak instead, where you can earn up to 5x points per $1 spent on an airline ticket.
