If you've ever needed a day off, you know how a duty swap usually goes. You post in the base WhatsApp group, scroll back through days of messages, ask five people one by one, and find out that most of them are already working that day.

DutyFlip is built to take that hunt away.

How it works

Import your roster once. DutyFlip reads your roster from RosterBuster or from the roster PDF. Your month appears in the Planner: flights, layovers, standby, days off and leave.

See every swap that fits. Colleagues at your base offer the trips and days off they'd like to give away. DutyFlip checks each one against your roster and marks it Legal or Clash, so you can see at a glance which ones you could actually take.

Find out why something clashes. A clash isn't a dead end. DutyFlip tells you what gets in the way, for example your own flight on the Monday, and which of your duties you could offer back in return to make the swap work.

Offer your own trip in two taps. Tap a day in the Planner, tap Offer, and say what you'd like in return. Colleagues who can take it will see it.

Agree it in a private chat. When someone asks for your trip, or you ask for theirs, a private chat opens between the two of you. Once you've agreed, you put the swap through Crewing exactly as you do now.

Private by design

Nobody sees your roster. Colleagues browsing swaps see the trip on offer, not your month, and your name only appears to someone who asks for it. Roster PDFs are read and thrown away straight away; only the duties you confirm are kept.

More than swaps

Onboard lets you ask whether any DutyFlip crew are operating a flight when family or friends are travelling on it. Only crew who have opted in can be asked.

Before you ask for a swap, DutyFlip also gives you a guide check against UK flight time limits: duty, rest and recovery. It's a guide only; Crewing always makes the decision.

What it costs

Everything in DutyFlip is free while we grow, Pro features included. Around six months after launch we plan to introduce an optional Pro plan, at £1.99 a month or £19.99 a year, for unlimited swap requests, an alert the moment a swap you'd want is posted, matches picked out for you and Onboard requests. Importing your roster, offering trips, answering requests and chatting stay free for good.

DutyFlip is independent and isn't affiliated with any airline. It's made by airline crew, for airline crew.
