Ryanair tried to catch me but it slipped in perfectly. That compression is actual Magic. Saved £70 on my first flight home!

No More Gate Anxiety
Everything you need to know about the bag airlines hate.
Does it really fit Ryanair? Plus
It is built exactly to 40x30x20cm. These are the specific dimensions required by Ryanair, easyJet, Wizz Air, and Jet2 to fit under the seat perfectly without any extra fees.
How does the guarantee work? Plus
If an airline forces you to pay a gate fine because of this bag's size, we will refund your entire purchase and cover the cost of the fine ourselves. Zero risk.
How much can I actually fit in it? Plus
A full week of clothes. Seven t-shirts, five jumpers, three pairs of jeans, joggers, underwear and socks, all compressed down with the vacuum pump. Most people cannot believe what fits until they try it.

Do I need the pump every time? Plus
No. The pump is only needed to compress the clothes compartment. Everything else in the bag works like a normal backpack. The pump is small and portable so it travels with you for repacking at your destination.

Is this better than just buying a cheap bag from Amazon? Plus
A cheap bag is not built to the exact sizer dimensions and comes with no guarantee. If it fails the sizer you pay the fine and still have a bag that does not work. The Onward bag is engineered to the millimetre and backed by a guarantee no other brand in this category offers.
What happens if it doesn't fit at the gate? Plus
It won't. The Onward Bag is built to 40×30×20cm - the smallest cabin bag limit of any airline in Europe. It's been tested against every major sizer, including Ryanair, easyJet, and Wizz Air. But in the rare event you're stopped unfairly, our Gate-Proof Guarantee has you covered: we'll refund the full cost of your bag and pay the gate fee ourselves. In 25,000+ flights, we've never had to.

The Latest Gate Victories
Real comments from passengers who just beat the sizer.
Nikki Evans
Saved £75 today at Stansted. The guy looked so annoyed when it fit perfectly. Best feeling Ever. Bag is worth every penny!
James Miller
Just did 5 days in Italy with ONLY this bag. The vacuum thing works wonders. Seriously stop paying for priority its a scam.
Chris Bolton
Actually arrived Next Day to Mayo. Quality is 10/10. My 16 inch macbook fits perfect in the back sleeve. Proper bag.
Hannah Gray
I was super skeptical about the promise but it literally slides in the cage. No more pre-flight stress for me. Finally.
S. Thompson
Wizz Air tried to pull me aside. Dropped it in the sizer and it sat there perfectly. She just waved me through. Sweet victory.
Liam Clarke
Used to pay £40 each way for priority. This bag paid for itself in one weekend trip to Prague. Do the math people!
Rebecca F.
The organization is GREAT. Passport pocket is so handy and the USB charging port kept me alive during the delay. Thanks Onward!
Michelle W.
I cant believe how much fits in here. The compression is better than my actual suitcase. Thinking about getting a second for hubby.
Alex Reed
Sturdy zippers and the waterproof material feels really high end. Definitely not a cheap knockoff. This is a legitimate travel tool.
Gary P.
Gate fees are daylight robbery. This bag is the only way to fight back. Fits under the seat so I have legroom too.
Julia Ross
Passed the Wizz Air sizer test yesterday. The attendant just stared at it. I smiled and kept walking. Totally worth it.
Tom Vance
If you fly budget often you need this. Its literally a cheat code for travel. Every traveler in the UK needs one.
