Understanding British Airways Baggage Policy
British Airways operates a tiered cabin bag policy where allowances depend on the fare type purchased rather than a single universal limit. Basic and economy fares are typically restricted to a small personal item that must be stored under the seat in front of you, with overhead locker access reserved for passengers who have purchased a higher-tier fare or paid a bag upgrade fee.
The distinction matters because gate fees for non-compliant bags are significantly higher than the cost of upgrading in advance. If your bag is borderline, measure it with all external pockets, wheels, handles, and feet included — these count toward the total, even though some manufacturers quote internal capacity only in their product listings.
On the TravelHub Strictness Scale, British Airways currently scores 6/10. A score of 6 indicates moderate enforcement. Gate checks happen regularly, particularly on busy routes and peak periods.
