The best flights from Washington DC to London

On shorter overnight flights, aim to find flights that are nearer or later than your usual bed time. This will help with dropping off to sleep.

The flights are also less likely to land when you'd typically be in deep sleep in your Washington DC timezone. Remember, you'll typically be offered breakfast 1-2 hours before landing too. That will feel easier nearer 6-7am on your body clock than 1-2 am.

Virgin Atlantic's A330neos feature their best hard products in every cabin. Even in Economy, it is a markedly better product with plenty of twin seats thanks to the 2-4-2 configuration. That's great for couples and groups. Solo travellers have fewer 'strangers' to navigate. There's easiest aisle access for window seat lovers. Huge screens, bluetooth for your own headphones, and deep recline.

Premium Economy comes in a 2-3-2 setup.

Business Class gets the latest Upper Class Suite with forward-facing suites with doors and aisle-access. These give the best setup for sleep, work, and window-gazing. You can also book extra space in their new 'Retreat Suite' as an individual or couple.

Studies show the effects of lower cabin altitude (more oxygen and humidity) help with feeling less fatigued when you land.

787s, A350s and A380s have lower cabin altitudes than other aircraft. On long flights, like from London to Washington DC, you'll notice your skin, mouth, and nose dry through the flight.
