Avoid extra fees at the gate
-
Measure your packed bag
For Wizz Air, handles and wheels are excluded; wheels may add no more than 5 cm. Side pockets count. Follow your airline’s measurement rules.
-
Choose a soft bag
A flexible backpack is often easier to fit in the baggage sizer than a hard-shell case.
-
Add bags before travel
Adding Priority or checked baggage online is usually cheaper than paying at the gate.
Choose the right kind of baggage
Before packing, separate three questions: what your fare includes, what you may bring into the cabin, and what you must hand over before security. A small backpack and a checked suitcase are different services. Paying for a bag in the hold does not automatically entitle you to bring a large trolley on board. Read the booking summary for every passenger and every flight segment. Your outbound and return journeys may have different allowances, particularly if you added baggage after the original booking.
Put your booking summary beside your packing list and assign every bag to an allowance. Measure the bag when fully packed rather than relying only on the manufacturer’s label. A soft bag can bulge beyond its advertised dimensions. Weigh your suitcase again after the final packing session and leave room for purchases on the way home. Keep a note of the baggage option you selected. A clear packing plan is more useful than hoping an extra item will go unnoticed at the gate.
Checked baggage: weight and dimensions
Ryanair offers checked bags of 10, 20 or 23 kg. The permitted number depends on the option selected. Its general maximum for an individual item is 32 kg and 80 × 120 × 120 cm; this ceiling does not replace the lower weight allowance you purchased. Wizz Air offers checked bags of 10, 20, 26 or 32 kg, with maximum dimensions of 149 × 119 × 171 cm. Its basic fare does not include checked baggage.
Choose an option based on actual weight as well as suitcase size. Keep travel documents accessible before handing over your bag. At the terminal, check the correct desk and retain the baggage receipt. For sports equipment, unusual dimensions or several suitcases, review the airline’s relevant special baggage rules before travelling. An item that is light but bulky does not automatically qualify as an ordinary checked bag. Our check-in guide explains the next steps at the terminal and helps you allow time for dropping off your bags.
Liquids and security at Memmingen
Memmingen Airport’s published security instructions still specify containers of no more than 100 ml in a transparent, resealable bag with a maximum capacity of one litre. Liquids and electronic devices should be placed separately in the tray. Do not rely on more generous rules you may have seen at another airport. The instructions at your actual screening point matter. The airport describes separate provisions for baby food needed during the journey; clarify special medical requirements with the appropriate service before travelling.
Pack the liquids bag last so you can remove it without searching through your luggage. A large bottle that is only partly full is not a substitute for a small container. Include creams and other gel-like products in your packing check. Empty your drinking bottle before security and use the collection facilities provided. Have your boarding pass ready, empty your pockets and follow staff instructions. Preparing these small details at home avoids having to reorganise your entire backpack while other passengers wait behind you at the screening belt.
Compare baggage charges carefully
There is no single baggage price that applies to every flight. Check the amount inside your airline booking and on the official fee page. Compare equivalent services: Priority with an additional cabin trolley is different from checked baggage. Also establish whether the quoted amount applies to one passenger, one bag and one direction. Include both directions when comparing the cost of a return trip, rather than assuming that a single add-on covers your whole holiday.
For your own comparison, total the add-ons for the bags you actually plan to take and compare that with the relevant fare bundle. A bundle is useful only when you need its included services. Bags that exceed size or weight allowances may attract additional charges, and repacking at the airport also takes time. Check binding amounts during the current booking process instead of relying on a permanently fixed example. Official Ryanair and Wizz Air fee links appear below. Parking and shuttle transfers are separate services governed by our parking prices.
Frequently asked questions
Is a 10-kg suitcase automatically cabin baggage?
No. A 10-kg checked bag must be handed over before security. A large cabin trolley needs the appropriate cabin baggage option. Read the service description in your reservation rather than relying solely on the weight printed on your suitcase.
Can I rely on newer scanners allowing larger liquid containers?
No. For Memmingen, plan around the published 100-ml container and one-litre bag instructions. Changes at other airports do not automatically apply to your departure. Follow the current instructions at the screening point on your travel day.
When should I check my baggage allowance?
Check before packing and again before departure. Include the return flight, the number of bags and the passenger to whom each allowance belongs. This helps you add genuinely needed services deliberately and avoid buying unnecessary extras.
