That €19 Flight Can Quickly Become €110
European ultra-low-cost carriers like Ryanair, Wizz Air, and EasyJet offer astonishingly cheap headline airfares. However, their business model relies on ancillary fees charged to passengers who fail to read the fine print.
The Four Major Hidden Traps
1. The Airport Check-In Penalty
Ryanair and Wizz Air require passengers to check in online via their mobile app prior to arriving at the airport.
- Ryanair: Online check-in closes 2 hours before departure. If you fail to check in online and check in at the airport counter, you will be charged a mandatory €55 / £55 per passenger fee.
- The Rule: Always download the airline app and check in on your phone the moment check-in opens (24 hours prior for standard ticket holders).
2. The Personal Item Sizer Trap
Basic fares on Ryanair and Wizz Air permit only one small personal item that must fit completely under the seat in front of you (Ryanair: 40 x 20 x 25 cm; Wizz Air: 40 x 30 x 20 cm).
- If your backpack exceeds the dimensions or does not slide into the metal gate sizer, gate agents will charge an airport gate fee of €35 to €50 and force the bag into the hold.
- Use our interactive Airline Bag Checker to verify your bag’s dimensions against exact carrier regulations.
3. Remote Secondary Airports
Budget airlines frequently fly to secondary airports located far outside the destination city:
- Paris Beauvais (BVA): Located 85 km from central Paris; the airport shuttle bus costs €17 each way and takes 1 hour 15 minutes.
- Frankfurt Hahn (HHN): Located 125 km from central Frankfurt; the bus costs €19 and takes 2 hours.
- Milan Bergamo (BGY): Located 50 km from Milan; the bus costs €10.
Always calculate the cost and time of the connecting airport coach when evaluating whether a budget flight is truly cheaper than the train.
4. Boarding Pass Printing Rules
Ryanair accepts digital boarding passes on their mobile app in almost all European airports, with a few notable exceptions outside the EU (such as Morocco and parts of the Balkans) where you must show a printed paper boarding pass stamped at the check-in desk. Check your confirmation email for the phrase 'Paper boarding pass required'.
