The best backpack for the airplane as free hand luggage is the Tech-Protect Defender S50 (139 PLN): capacity 20 l, dimensions 40 × 20 × 25 cm fitting within the current frame of Ryanair and Wizz Air (40 × 30 × 20 cm), dedicated compartment for a laptop up to 15.6″. Premium version: Tech-Protect Defender S40 (229 PLN) with hybrid material resistant to moisture. For passengers with a 16″ laptop, the best backpack for the airplane is UAG Civilian 20L (539 PLN). Below is the full ranking of 7 models for every budget.
A cheap flight is now a lottery with luggage. From September 2025, Ryanair accepts free luggage under the seat up to 40 × 30 × 20 cm, Wizz Air has the same limit for the basic fare, and LOT allows a personal item 40 × 35 × 12 cm plus full hand luggage 55 × 40 × 23 cm. A backpack for the airplane that does not fit in the gate frame costs from 70 PLN (priority online purchase) to 80 euros (extra charge at the airport). We have gathered 7 backpacks from the offer of homescreen.pl that have truly passed the size test. Check which backpack from Ryanair, Wizz Air, or LOT suits your travel style.
What a good airplane backpack must have
Before comparing specific models, check six key criteria. This is the absolute minimum for anyone flying with low-cost airlines who does not want to pay extra for luggage.
- Dimensions under the seat: currently 40 × 30 × 20 cm on Ryanair and Wizz Air (basic fare, change from September 2025). Backpacks with the older dimension of 40 × 20 × 25 cm still fit in the frame with some margin. The backpack must have reinforced sides to fit in the control frame.
- Capacity 18–25 l: below 18 l you can only fit a weekend’s worth, above 25 l the backpack physically won’t fit under the seat. The golden mean is 20 l.
- Dedicated laptop compartment: minimum 14″, ideally 15.6″ or 16″. Padded, separated from the main compartment.
- Moisture-resistant material: hybrid fabrics or 600D polyester with a PU coating. In the rain at the airport, it’s the difference between a wet and dry laptop.
- Luggage strap (trolley sleeve): allows you to slide the backpack onto the handle of the suitcase when transferring between flights.
- Ergonomic back and chest strap: 8 hours of layovers in Istanbul ruthlessly tests the design of the straps.
Secondary, but worth noting: hidden anti-theft pocket, compatibility with AirTag, USB port for charging a power bank inside, YKK zippers with the option to attach a TSA lock.
Tip: The backpack dimensions in the specifications are „empty” dimensions. When packed, the backpack stretches by 2–4 cm in every direction. Leave some margin; the model 40 × 20 × 25 cm when packed can realistically measure 42 × 22 × 27 cm and won’t pass the frame.
Dimensions of carry-on luggage, comparison of airlines
Each carrier has its own baggage policy. The table below collects the limits for the most popular airlines operating in Poland in 2026.
| Airline | Small baggage (free, under the seat) | Large carry-on baggage | Max. weight |
|---|---|---|---|
| Ryanair | 40 × 30 × 20 cm | 55 × 40 × 20 cm (Priority) | 10 kg (large) |
| Wizz Air | 40 × 30 × 20 cm (10 kg) | 55 × 40 × 23 cm (Priority) | 10 kg |
| LOT | 40 × 35 × 12 cm (personal) | 55 × 40 × 23 cm (main) | 8 kg (main) |
| Lufthansa | 40 × 30 × 10 cm (personal) | 55 × 40 × 23 cm (main) | 8 kg (main) |
| EasyJet | 45 × 36 × 20 cm | 56 × 45 × 25 cm (Plus/Flexi) | 15 kg |
| Buzz | 40 × 30 × 20 cm | 55 × 40 × 20 cm (Priority) | 10 kg (large) |
| Enter Air | 40 × 30 × 15 cm (personal) | 55 × 40 × 25 cm | 5 kg |
Conclusion: Today, the current standard for a backpack for the airplane is 40 × 30 × 20 cm (Ryanair, Wizz Air, Buzz in the basic fare, Lufthansa as a personal item). Backpacks with the older dimension of 40 × 20 × 25 cm (e.g., Tech-Protect Defender S40 and S50) are still fully compliant, as they fit into the new, larger frame with some margin. If you fly with LOT or Lufthansa and do not need a separate suitcase, you can take a backpack of 55 × 40 × 23 cm as full carry-on luggage included in the ticket price.
Note: Airlines regularly update their regulations. Always check the latest version on the carrier’s website before departure, link to the official policy of Ryanair and Wizz Air.

Which airplane backpack to choose? Recommendations based on needs
The choice of an airplane backpack depends on three variables: how often you fly, whether you pay for priority, and how large your laptop is.
- If you fly with Ryanair or Wizz Air on a basic fare (without priority), the current frame under the seat is 40 × 30 × 20 cm. The best options are Tech-Protect Defender S50 or S40 (40 × 20 × 25 cm, fit with some extra space) and Uniq Arden RPET 18L.
- If you are buying Priority for 15–25 PLN, you have a free choice. UAG Civilian 20L offers the best value for money, UAG Premium Tech wins when you need fully waterproof zippers.
- If you are flying for 3–5 days with a laptop, TOMTOC Navigator T66 will replace a small suitcase and still fits in the Priority cabin baggage.
- If you are packing a 16-inch laptop (MacBook Pro M5, Lenovo ThinkPad X1), skip S40/S50/Uniq (max. 15.6″) and choose any model from UAG or TOMTOC.
- If your budget is up to 200 PLN, Tech-Protect Defender S50 is the only reasonable choice for an airplane backpack.
- If you care about recycled material, go for Uniq Arden RPET 18L: an eco-friendly airplane backpack made from recycled PET bottles.
- If your budget is 500–900 PLN, aim for UAG Civilian (daily travel) or UAG Premium Tech (intensive professional use).
Our editorial choice: Tech-Protect Defender S50 for 90% of low-cost airline passengers. It meets the limit, costs less than a second ticket for excess baggage, and will last for several years.
What to pack in your airplane backpack, checklist
Cabin baggage with Ryanair is max. 10 kg, but realistically 6–8 kg of clothes and equipment fits. An optimal list for a 3-day trip:
- Electronics (for separate compartment): laptop, charger, USB-C cables, power bank (max 100 Wh, airline limit), headphones, phone charger.
- Documents (front pocket, quick access): passport or ID, boarding pass, insurance, credit card.
- Clothes (rolled, not folded): 2 t-shirts, 1 shirt, 1 sweater, 2 pairs of socks, 2 pairs of underwear, 1 spare pants.
- Toiletries (up to 100 ml per container, max 1 l total): toothbrush, toothpaste, deodorant, perfume in a container.
- Accessories: water bottle (empty at security), AirTag in the inner pocket, sports bottle, car charger for the trip from the airport, wireless headphones for a long flight.
Tip: The suitcase strap (trolley sleeve) also works for cabin luggage. Sliding the backpack onto the handle of the Priority suitcase frees your arms and allows you to run through Heathrow without compromising your back.
Practical tips before departure
Three things that 5% of passengers do, but 100% should.
- Measure your backpack after packing, not empty. Compare the updated dimensions with the frame at the gate, 1 cm too much is a 70 PLN surcharge.
- Pack your laptop in the main compartment, not in the laptop compartment, security control requires removing electronics, it’s easier from the main one.
- Keep your power bank in your backpack, never in checked luggage. Lithium-ion batteries cannot fly in the hold.

FAQ, frequently asked questions
What backpack for carry-on luggage on Ryanair?
The current limit for free carry-on luggage on Ryanair is 40 × 30 × 20 cm (as of September 2025, previously 40 × 20 × 25 cm). The backpack must fit under the seat in front of you. The best options are Tech-Protect Defender S40 and S50, as well as Uniq Arden RPET, because their dimensions are smaller than the frame and fit comfortably even when fully packed.
Will a backpack measuring 40 × 30 × 20 cm fit in Ryanair?
Yes. 40 × 30 × 20 cm is the current maximum size for free baggage on Ryanair (change from September 2025). Backpacks that fit exactly within this size (e.g., Uniq Arden RPET) fit without any issues. If the backpack is packed to the edges and slightly bulging, it’s better to choose a smaller model, like Tech-Protect Defender S50 (40 × 20 × 25 cm), to avoid any risks at the gate.
What backpack for Wizz Air as free baggage?
The free carry-on baggage on Wizz Air (Standard fare) is 40 × 30 × 20 cm and max 10 kg. Tech-Protect Defender S40 and S50 (40 × 20 × 25 cm) will fit with room to spare, and the Uniq Arden RPET 18L backpack will also fit without any problems. If you purchase the WIZZ Priority or WIZZ Plus fare, the limit increases to 55 × 40 × 23 cm, so any backpack from our ranking will fit as free baggage.
What backpack for LOT Airlines?
LOT Polish Airlines allows you to take carry-on baggage of 55 × 40 × 23 cm and 8 kg included in the ticket price, plus a small personal item of 40 × 35 × 12 cm (max 2 kg). In the „full baggage” category, UAG Civilian 20L, UAG Premium Tech 24L, and TOMTOC Navigator T66 will work great, utilizing the entire limit. Tech-Protect Defender or Uniq Arden will fit as a personal item.
How much does a good cabin backpack for a plane cost?
A good cabin backpack for the plane starts at 130–150 PLN (Tech-Protect Defender S50) and goes up to 800–900 PLN (UAG Premium Tech). Backpacks in the 200–400 PLN range from brands known for mobile accessories (Tech-Protect, Uniq, TOMTOC) offer the optimal quality-to-price ratio for someone flying 5–10 times a year.
Can I take a laptop in a cabin backpack?
Yes, a laptop in carry-on luggage is standard. Most travel backpacks have a dedicated padded compartment for laptops up to 15.6″ or 16″. At security control, you must remove the laptop from the backpack and place it separately in a container, as required by EU regulations for devices over 12″.
Can I take a power bank in a cabin backpack?
Power banks must fly in carry-on luggage, never in checked baggage. The capacity limit is 100 Wh (about 27,000 mAh) without airline approval, 100–160 Wh with approval. The backpack must keep the power bank accessible, as controllers often ask to remove it for separate inspection.
Will an AirTag in the backpack pass airport security?
Yes, the Apple AirTag is legal in both carry-on and checked luggage. The UAG Civilian backpack even has a dedicated hidden pocket for the AirTag, so in case of loss, you can locate the backpack through the Find My app. Check the full range of Bluetooth trackers at homescreen.pl.
What is the difference between Tech-Protect Defender S40 and S50?
S40 and S50 have identical dimensions (40 × 20 × 25 cm), capacity (20 l), and laptop compatibility (15.6″). The differences are in the finish and price: S40 (229 PLN) has sturdier seams, a stiffer bottom, and a classic black that matches a suit. S50 (139 PLN) is the olive version, with a lighter construction, sufficient in 90% of cases.
