Official site: britishairways.comBritish Airways is the dominant carrier at Heathrow and the most common way to reach the UK from the United States. Its long-haul operation splits across Terminals 3 and 5, which is the detail most worth knowing in advance, because the two are a shuttle ride apart and a connection between them is not a short walk.
The cabin names take a moment to decode. World Traveller is long-haul economy, World Traveller Plus is premium economy, Club World is business and First is a separate cabin above that. On short-haul European flying the names change again to Euro Traveller and Club Europe, which describe a different product entirely from their long-haul equivalents.

How British Airways baggage works
British Airways structures allowance by cabin and fare type, with the entry-level hand-baggage-only fares on some routes being the ones to watch. Status in the loyalty programme and oneworld tier add entitlements on top.
Long-haul tickets are counted in pieces with a per-bag weight ceiling rather than a single combined weight. Hand baggage on BA is relatively generous by European standards, typically allowing a cabin bag plus a personal item, but the enforcement of size at the gate is real on full flights.
Confirm the allowance attached to your booking on britishairways.com, particularly on itineraries that include a partner-operated segment where different rules can apply.
Check-in
Online check-in generally opens 24 hours before departure, and BA's app holds the boarding pass and pushes gate information.
Heathrow bag-drop cutoffs are firm and earlier than the check-in deadline. At a hub of that size, the walk from security to a remote gate can itself take twenty minutes, so the published cutoff is not a target to aim for.
Boarding
Boarding is by numbered group shown on the boarding pass, ordered by cabin and status, with hand-baggage-only and entry fares toward the end.
On full long-haul departures, overhead space in economy runs out before the last group boards. If something must stay with you, keep it in the item that fits under the seat.
Before you fly British Airways
Check whether you are at Terminal 3 or Terminal 5
Both handle BA long-haul at Heathrow. They are connected but not adjacent, and a connection between them needs materially more time than one within a single terminal.
Club Europe is not Club World
Short-haul business on BA is a standard economy seat with the middle seat blocked and a different service. Long-haul Club World is a lie-flat cabin. The shared word does a lot of misleading work.
Watch for hand-baggage-only fares
On several routes BA sells a fare with no checked bag included. It is clearly labelled at booking but easy to skim past when comparing prices across airlines.

FAQ
British Airways — common questions
General guidance only. British Airways sets these policies and can change them, so confirm anything that affects your trip at britishairways.com.
What is the difference between World Traveller and World Traveller Plus?
World Traveller is British Airways' long-haul economy cabin. World Traveller Plus is its premium economy: a separate cabin with a wider seat, more recline, more legroom and a different baggage allowance and service. It sits between economy and Club World business class rather than being an extra-legroom row within economy.
Which Heathrow terminal does British Airways use?
BA operates from both Terminal 5 and Terminal 3 at Heathrow, with the split depending on the route. Terminal 5 is its main base. Because the terminals are linked by transit rather than walkway, confirm which one your flight uses before travelling, and allow extra time if you are connecting between them.
How much hand baggage does British Airways allow?
BA has historically been more generous on cabin baggage than most European carriers, typically permitting a cabin bag plus a personal item across cabins. Dimensions and enforcement do change, and gate checks on full flights are genuine, so verify the current sizes on britishairways.com against the bag you plan to bring.
