What is the best free bag size for this group?+
A bag no larger than 40 × 30 × 20 cm (15.7 × 11.8 × 7.9 in), up to 10 kg fits the free bag allowance on all 3 airlines in this group — the limit is set by Ryanair.
Why not just buy the biggest bag?+
Because the strictest airline in the group wins. A bag that fits Ryanair fits everyone here; a larger one would be rejected or charged there. Buy for the tightest limit and you’re safe on all.
Should I leave a safety margin?+
Yes — measure with wheels and handles, and pick a bag a touch under the limit. A packed bag bulges, and low-cost airlines measure strictly at the gate.
