How to fly Ryanair with the right bag

That is the first thing to fix, because people search for a cheap cabin bag line item and never find one.

What Ryanair sells is four separate things. Every fare, Basic included, carries one small bag of 40 x 30 x 20 cm that goes under the seat in front. It is one bag, not two, so a handbag plus a laptop bag is already over the allowance.

The 10 kg overhead trolley, 55 x 40 x 20 cm, cannot be bought on its own at any price. It exists only inside Priority and 2 Cabin Bags, which also gives you priority boarding and keeps the small bag as a second piece.

Then there are the hold bags: 10 kg, 20 kg and 23 kg, dropped at a desk before security. Confusingly the 10 kg hold bag is the same size as the trolley. The difference is where it travels, not what it holds.

Work out which of the four you need before you look at a single price.

Ryanair publishes a real band for every bag, and the band is wide because the price moves with the route and the dates. Every one of them is charged per passenger, per one-way flight.

Priority and 2 Cabin Bags runs €12.49 to €36. A 10 kg hold bag runs €10.49 to €44.99. A 20 kg hold bag runs €21.49 to €59.99, and you can take up to three of them. A 23 kg hold bag runs €28.99 to €80.99, capped at one per passenger, and it is the most expensive routine bag Ryanair sells.

Excess weight on any hold bag is €13 for each extra kilo, charged at the airport.

Two Sofia travellers flying a return with one 20 kg bag each are buying four bag events, not one. At the middle of that band it is more than most of the fares on this site.

Price them against each other rather than assuming the cabin route is cheaper. Priority and 2 Cabin Bags runs €12.49 to €36 at booking. The 10 kg hold bag runs €10.49 to €44.99. The bands cross, so on any given flight either one can be the cheaper answer.

They buy different experiences. The trolley stays with you, boards early and needs no desk, but it has to pass the gate sizer. The hold bag has no sizer risk at all and no boarding queue, but you must arrive early enough to drop it before security, and you wait for it at the other end.

For a two-night trip where the bag is soft and half empty, the trolley usually wins. For anything you would rather not repack in front of a queue, the hold bag is the calmer purchase at a similar price. Check both numbers in the same booking session before you choose.

Priority and 2 Cabin Bags is capped per flight and it does sell out. Ryanair publishes a help article for exactly this situation, and its own advice is blunt: if Priority is gone, buy a 10 kg check-in bag instead.

That fallback is not the same trip. The check-in bag has to be dropped at the bag desk before security, so a passenger who planned to walk straight to the gate with a trolley now needs to arrive earlier and stand in the bag drop queue.

The practical consequence is a timing rule rather than a price rule. If you know you want the trolley, buy it in the first booking, not the week before. Leaving it late risks paying more, and it risks the product not being on sale at all.

This is also why Priority is worth deciding on before you compare fares. A fare that only works with a trolley is not really that fare.

Most of the money lost on Ryanair is lost right here, by buying a bundle that does not contain the bag you needed.

Basic is the fare plus the free under-seat bag. Regular adds Priority and 2 Cabin Bags and a standard seat, and includes no hold bag. Plus adds a 20 kg hold bag and a seat, and includes no trolley and no priority. Flexi Plus carries two cabin bags, fast track and a free date change, and again no hold bag. Family Plus is the unusual one: a 10 kg bag for every group member plus one 20 kg family bag for the whole booking.

So Regular and Plus solve opposite problems, and buying the wrong one costs you the bundle and the bag.

Which? ran the bundle against a Basic fare plus the identical extras around thirty times over two years and found the bundle cheaper exactly once. Price both in the same session before choosing.

This is the strongest evidence on the page, because it is not folklore. Ryanair's fee table has two price columns, one for the time of booking and one for afterwards.

Priority and 2 Cabin Bags goes from €12.49 to €36 at booking, and €19.99 to €45.50 afterwards. A 10 kg hold bag goes from €10.49 to €44.99, and €24 to €75 afterwards. A 20 kg hold bag goes from €21.49 to €59.99, and €39.99 to €75. A 23 kg hold bag goes from €28.99 to €80.99, and €54 to €97.

At the bottom of each band, waiting costs between 60 and 129 per cent more. That is a published price structure, not a guess about drip pricing, and it is the single clearest reason to settle the bag question before you pay for the seat.

The same figures apply from Sofia and Plovdiv. Ryanair's Bulgarian fee table carries the identical euro bands as its Irish one.

The received wisdom says always add it online. For one specific tier that is measurably wrong.

Ryanair publishes a flat airport bag-drop price of €35.99 for a 10 kg hold bag, while the post-booking online band for the same bag runs up to €75. If you missed the booking window and the app is quoting you more than €35.99, the desk is cheaper.

The conditions are narrow and worth repeating. It applies to the 10 kg tier only. It applies at the bag-drop desk only, never at the boarding gate, which is a separate and much more expensive counter. And it only works if you are at the airport early enough to use the desk before it closes.

The 20 kg tier has a flat desk price too, €59.99, which sits at the top of its own online band rather than below it. So the exception really is one tier wide.

Passengers on the same booking who have hold bags can split the combined weight however they like. Two 20 kg bags can travel as 15 kg and 25 kg. The only hard limit is 32 kg for any single piece.

That turns one question into a cheaper one. Two people going away for four nights rarely need two trolleys. One 20 kg hold bag, shared, often costs less than two Priority purchases, and it removes the gate sizer from the trip entirely.

Run the arithmetic with the real quoted prices rather than the advertised floors. At the middle of the bands, two Priority purchases for a return is four charges, and one shared hold bag for a return is two.

The method generalises. On Ryanair the cheapest answer is usually the one with the fewest chargeable bag events, not the one with the smallest bag.

There are two separate gate charges and most guides confuse them.

Bring a cabin bag that will not fit the sizer and Ryanair charges €70 to €75 to put it in the hold. Bring a hold bag you paid for to the gate instead of the bag desk and it is €46 to €75. Both are per bag, per one-way flight, and both are Ryanair's own published figures.

Enforcement has tightened. Travel press through 2026 reported that gate staff bonuses for spotting an oversize bag rose to about €2.50 per bag in November 2025 with the monthly cap removed. Ryanair has not confirmed those amounts, so treat the exact figure as reported rather than official. The direction is consistent across sources, and it is the part worth acting on.

The sizer is a rigid frame and your bag is expected to drop in unaided. Pack to the size, then check it packed.

Ryanair's own help centre states that you cannot take a cabin or check-in bag off a booking or get a refund once it is bought. Buying one just in case is a one-way decision, so make it deliberately.

Two more charges catch people who thought they were done. Checking in at the airport rather than online costs €55 per passenger per sector, and the free airport check-in that used to sit inside Plus and Flexi Plus now applies only to bookings made before 14 August 2025. Travelling with a lap infant costs €25 per infant per one-way flight, though the infant does bring a 5 kg baby bag of 45 x 35 x 20 cm plus two free items of baby equipment.

None of that is unusual for a low-cost carrier. It is only expensive when you meet it at the airport instead of at the booking screen.
