Guide to Book a Cheap Flight from London to Washington?

Cheapfaremart is committed to provide you the best available airfare. However, some practical travel hacks based on real-life experience are worth of getting your attention.

1. The cheapest time of the day to depart from London to Washington

Departures with a redeye flight to Washington are usually cheaper than the regular hour departures. The reason is obvious – sleep deprivation. You shouldn’t mind spoiling a few hours of comfortable sleep if it helps you grab some discount flight to Washington. However, make sure to reach the departure airport on time at least 3 hours before the flight departure.

2. The cheapest day of a week to fly from LON to WAS

Flight departures on a mid-weekday like a Tuesday, Wednesday or Thursday are often cheaper than the weekend departure particularly on a Friday late night, Saturday and Sunday. Weekend vacationers throng in Washington to unwind and relax. Airlines often raise their fare level to take advantage of the trend.

3. The cheapest months of a year to fly to WAS from LON

November to February are the cheapest months, but the weather is not favorable for a leisure vacation. Let the extreme winter season ends. Depart for a rewarding Washington vacation in spring from March to April. Or make your trip when the fall commences but mind the key festival season when fares may take you by surprise.

4. The cheapest airlines to fly from London to Washington

Flybe is the only budget carrier on the route LCY to Washington Dulles Airport IAD. We recommend you confirm your air ticket to Washington at least 21 days before the departure date.  While booking cheap flights to Washington or any other route, make sure you don’t ignore the terms associated with cancellation and refund. Remember, life is full uncertainties.
