The best flights from Orlando to London

These overnight flights will be easier to sleep through. Your body clock will still be on your Orlando timezone, so getting to sleep will be easier for flights after 9pm. By the time dinner is cleared away, it will be about 11pm and you'll feel naturally tired.

The second big benefit is that the flights will land nearer a time you would typically wake up in Orlando. Your body will have had more chance to rest and recharge without interruption at a somewhat normal time. Earlier flights will leave you sleep deprived. 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.

If you do have to take an earlier flight, see if you can get the earliest possible flight then get home or to a hotel for a "proper" sleep until lunchtime in London the day you land (your body will want to this anyway). If you can land around dawn, get out the airport quickly, and beat the morning rush hour traffic home, this also works. Your flight then isn't so critical for sleep.

Virgin's oldest Upper Class cabin divides fans. The design was first offered in 2003. You'll have the same onboard service, but the seat design is much narrower, angled towards the aisle with less privacy and little storage compared to modern configurations. Window gazers will find it frustrating trying to look out at a narrow angle while facing towards the middle of the cabin.

All the seats have aisle access, and these beds benefit from no obstruction to your feet so they're good for sleeping. These are also the only remaining aircraft with the onboard bar. The A330-300s will be out of the fleet by 2028, and the last 787-9 will be reconfigured by 2030.

Until then, you may get more for your money by booking an alternative cabin - either another Virgin flight, or an alternative airline with a more modern business class configuration.

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 Orlando, you'll notice your skin, mouth, and nose dry through the flight.
