British Airways

British Airways is the flag carrier for people flying into and out of the UK, with Heathrow as its main nerve centre and a network built around long-haul routes, city links and oneworld connections. By our assessment, it does the big-airline job well when the plan is to cover a lot of ground from one hub and tie into partner flights. The trade-off is the usual one for a legacy carrier: fares and service can feel tied to tiers, cabins and crowded airports, not to simplicity. In practice it means terminals, baggage rules, seat classes and a lot of moving parts, which is fine if you want a full-service network and less appealing if you want the cheapest bare-bones hop. It sits above low-cost point-to-point carriers and below the fantasy of a perfectly smooth trip. British Airways is for travellers who want reach and schedule rather than frills, and the Heathrow experience is the part that most shapes the day.
