A low-cost transatlantic service will not really be worth it, primarily because airfares during the winter are already low to very low - you can normally fly LON-NYC for about 180 GBP with BA
, so about 90 GBP each way. You couldn't shave much off that at all. The only real possibility is to acquire old 747s or DC-10s and operate during the summer only, when fares are normally expensive to very expensive - it's normally 400 GBP or more to fly from LON to NYC. But this would have be impractical: what do you do with the staff and aircraft during the winter, when they're not needed? It would be inefficient. Also, low-cost airlines generally operate short routes and thereby have excellent aircraft and staff utilisation, which helps to reduce costs. But if an airline began transatlantic flights, it'd only be able to do one round-trip per day. Again, it'd only be worthwhile during the summer, but then there would be major problems to overcome. I guess you could possibly have two distinct seasons and operations: during the winter, you could - on a low-cost basis -fly to Lagos, Tokyo, Nairobi, etc., which are normally very expensive to get to when flying non-stop, and, during the summer, fly to the USA only, again on a low-cost basis. This would solve the problem of the what to do with staff and aircraft during the winter.
