Fly budget airlines without paying for checked bags

To avoid checked bag fees, you must stick strictly to a single personal item that fits under the seat. If you need more space, purchase your overhead cabin bag online during booking rather than at the airport gate, where fees are typically double.

  1. Measure your bag accurately. Most budget airlines (like Ryanair or Spirit) have strict dimensions for a 'personal item.' Measure your bag before you leave the house—it must fit under the seat in front of you. Aim for dimensions like 40cm x 30cm x 20cm (16in x 12in x 8in).
  2. Wear your heavy gear. If you are struggling to fit everything in, wear your heaviest items—boots, jackets, and hoodies—onto the plane. This saves significant volume and weight in your bag, which is usually restricted to 7-10kg.
  3. Use a soft-sided bag. Hard-shell suitcases have rigid frames that don't squeeze into sizing bins. A soft-sided backpack or duffel bag allows you to compress the shape to ensure it fits the airline's sizing template.
  4. Book your carry-on in advance. If you absolutely need an overhead cabin bag, add it to your booking at least 24 hours before your flight. Buying 'priority boarding' or 'cabin bag' access online is usually 50% cheaper than paying at the gate.
  5. Consolidate liquids and toiletries. Buy toiletries at your destination or use what your accommodation provides. Packing full-sized bottles forces you to check a bag; using 100ml travel-sized containers keeps you in 'carry-on only' territory.
Will they weigh my personal item?
Rarely, unless it looks obviously oversized or heavy. Focus on the physical dimensions first.
Can I bring a duty-free bag?
Most airlines count your duty-free bag as part of your luggage allowance. If you are already at your limit, do not buy items at the airport.
