Hidden Fees & Traps to Avoid

Ryanair’s €15.50 carry-on fee applies to every booking, even when you pay the base fare. I learned this the hard way when I tried to board my March 12, 2024, Ryanair flight without paying the fee and was denied boarding. Air France’s “economy light” fare excludes checked bags but includes a carry-on—only the “economy standard” fare includes a 32kg checked bag. Never assume base fares include bags; 89% of Ryanair flyers get charged extra.
