Why enforcement varies at London Stansted Airport

Check-rate percentages are calculated from approved traveller outcomes for each airline at STN. A high rate means travellers are often being stopped, measured, or charged on that airline from this airport. A lower rate does not remove the rule, but it suggests the gate is less likely to turn every borderline bag into a hold-bag payment.

Gate agents work for the airline, not the airport, so two adjacent gates can behave very differently. Low-cost carriers operating narrowbody aircraft with tight overhead space usually enforce most aggressively, especially when the boarding queue is full and staff need to protect locker space.

Time of day and load factor can amplify checks. Busy morning and evening departures often feel stricter than quieter off-peak flights. Use this page with the airline heatmap when deciding whether to pre-book baggage or keep the fare carry-on only.
