BA's problem is their long haul aircraft are very premium seating heavy, so the total capacity isn't that much of a jump over a 321 short haul. It would be a different story if they had densified long haul aircraft. As an example some BA 777's are 299 passengers, while Air Canada has 777's that seat 458.
