Carry-On Only for Kraków: Ryanair, Wizz Air, and Packing Tips

Kraków is served primarily by two of Europe's strictest budget carriers. Ryanair and Wizz Air dominate KRK routes, and both enforce their bag size rules aggressively at the gate. Getting this wrong costs you 50 EUR or more at the last moment. The good news is that a well-chosen, soft-sided travel backpack handles both airlines' sizers, fits the cobblestoned streets of the Old Town, and makes the Auschwitz day trip significantly more practical. LOT Economy includes a main bag, but its8 kg limit still matters.

Airline Carry-On Comparison

Ryanair: Decide whether you need an overhead bag

Ryanair's base fare to Kraków includes only a 40×30×20 cm underseat personal item. At 40×30×20 cm, this is smaller than a standard laptop backpack. Anything larger will not fit under the seat.

Adding priority boarding unlocks overhead locker access with a 55 × 40 × 20 cm bag plus the underseat item, combined up to 10 kg. If your bag exceeds the free dimensions, check the paid allowance before booking.

Note that Ryanair's cabin bag size at 55 × 40 × 20 cm is shallower than many competitors at 23 or 25 cm depth. A bag that fits on easyJet at 25 cm depth may not pass the Ryanair sizer. Measure your bag's depth carefully before flying Ryanair.

Wizz Air: Check the purchased allowance

Wizz Air includes a 40×30×20 cm small bag up to 10 kg. WIZZ Priority adds a 55×40×23 cm trolley with its own10 kg limit. A55 cm roller can fit that trolley allowance; it does not fit the smaller free allowance. Compare the actual add-on quote before travel.

LOT Polish Airlines: Included main bag

LOT Economy, including Saver, includes one 55×40×23 cm main bag up to 8 kg plus one 40×35×12 cm personal item up to 2 kg. European Business allows two main bags up to 9 kg each; US flights have separate rules. Weigh the fully packed main bag and personal item separately; do not choose the carrier on the assumption of a 12 kg Economy allowance.

LOT also operates a Star Alliance codeshare network, which is useful for itineraries connecting through Warsaw (WAW).

Bag Sizers at KRK: What to Expect

Measure and weigh every packed bag against its fare allowance. A soft backpack is not guaranteed to fit when overfilled. Size, weight and piece count are separate checks. Do not rely on model names or litres as proof of fit.

Old Town Cobblestones: Why Backpacks Win

Kraków's Stare Miasto (Old Town) and the adjacent Kazimierz (Jewish Quarter) district are almost entirely cobblestoned. The Royal Road from the Barbican through Floriańska Street to the Main Market Square (Rynek Główny) is beautiful and completely impractical for wheeled luggage. The noise of a roller bag on Kraków's cobblestones is considerable and physically tiring over a day of movement.

A backpack:

• Clears cobblestones without effort
• Is easier to carry through Wawel Castle's steep courtyards
• Fits under market stalls and through narrow doorways in Kazimierz
• Is lighter to manage than a roller when navigating tram platforms

Auschwitz Day Trip

The Auschwitz-Birkenau Memorial and Museum is 70 km west of Kraków, accessible by a combination of coach or train from Kraków Główny station. Most visitors book a guided day tour from Kraków, with coaches departing early morning.

On the day trip:

• Bring only a small daypack (fits inside your carry-on) with water, snacks, and documentation
• Comfortable walking shoes are essential — the Auschwitz I and Birkenau sites involve significant walking across uneven ground
• Storage lockers are available at the Auschwitz visitor centre for larger items if needed

Polish Winter Packing

Polish winters (December through February) are properly cold, with Kraków temperatures averaging minus 2 to plus 2 degrees Celsius. Snow is common. Layering strategy:

• Thermal base layer top and bottom
• Fleece or wool mid-layer
• Insulated waterproof jacket (wear on the plane; not in the bag weight)
• Wool socks, warm gloves, and a beanie (light and compact)
• Waterproof ankle boots (wear during travel)

This combination packs into a 30–40 litre backpack with room to spare.

Practical Tips

• LOT: compare the complete booking price. Economy includes one 8 kg main bag and one 2 kg personal item; leave room for purchases within each limit.

The Bottom Line

Weigh your main bag and personal item separately after adding toiletries, chargers and purchases. Keep each within its own limit.
