Expedia

Searching flights on Expedia brings fares from many airlines into a single results page, with options for one-way, round-trip and multi-city itineraries. A key reason travellers use it for air travel is bundling: adding a hotel or car to a flight booking can lower the combined price compared with booking separately, depending on dates and destination. Flight purchases can earn OneKeyCash through One Key, the rewards programme shared with Hotels.com and Vrbo. Some fares are sold as basic economy, so seat selection, carry-on and change rules should be read before paying. Because Expedia sits between the traveller and the airline, managing changes after a schedule disruption may involve both parties. Shoppers comparing it with booking direct should weigh One Key rewards against airline-direct perks and the convenience of dealing with the carrier itself.
