Cheap Flights from Heathrow & London

1. Compare dates. If you can travel a day or two earlier or later, check multiple dates rather than just one.
2. Compare airports. Heathrow is the most convenient for Feltham, but other London airports can sometimes have different fares on the same route.
3. Check the total price. Look beyond the headline fare — baggage, seat selection and payment fees can add up.
4. Check the connection. A cheaper itinerary can mean a longer journey or a self-transfer — read the full itinerary before confirming.
5. Check the airport journey too. A cheap fare is less useful if getting to the airport is expensive or difficult at your departure time.

Feltham is one of the closest towns to Heathrow. See our Feltham Transport Guide for full details on buses, trains, fares and journey times to the airport, and our Feltham Taxis page for licensed local minicab firms.

Allow extra time for check-in, security and unexpected delays — always check the airport's own live travel information before leaving.

Is Heathrow always the cheapest London airport?

No. Fares vary by destination, date, airline and airport. Compare other London airports when your plans allow flexibility.

Is there a best day or time to book?

There's no reliable universal rule for the cheapest booking day. Comparing dates and checking the total fare and conditions matters more than timing a single "best day."

Are baggage fees included in the price shown?

Not necessarily. Airlines and fare types differ — always check the final fare conditions and baggage allowance before booking.

Does FelthamDeals operate the flights or take the booking?

No. FelthamDeals provides the search experience; the booking itself is completed through our travel partner, Travelpayouts, and its airline/agent network.
