For a long time, we've thought that a flight on London in the Sky is the most fun you can have without taking your clothes off. But now, we're asking people to do just that: to take a flight with us on 30 April, get completely naked, and raise crucial funds for two of our partner charities while you do so.

Bottoms Up is a flight with a difference. Men and women are invited to two separate flights on the morning of 30 April in aid of Movember and Coppafeel! respectively – charities that do incredible work in raising funds and awareness in the fight against health issues faced by men and women. Coppafeel! is a charity working to eradicate breast cancer, while Movember focuses on health problems faced by men today, from prostate cancer to mental health issues.

How does it work?

If you're eager to bare all for the two charities (although, if you're shy, you can leave your pants on) and you're interested in joining one of the flights, click on either of the below options and register your interest via the RSVP button. On 6 April, entrants will be drawn at random from the list of entrants. You'll need to cover the cost of your flight (£99) and you can make even more money for the two charities by seeking sponsorship from family, friends, colleagues and, hell, anyone on the internet. The ticket price and all funds you raise will be shared between Movember and Coppafeel!
