Very generally in Long Haul, but on the North Atlantic in particular, premium cabins and belly freight are where the profit is, economy class pax are there for ballast and to pay the fuel bill. Once the premium cabins are full, the economy fares can be sold quite low when needed. This is a big reason why low-cost long-haul has failed time and again on the NAT. There is a market for the package holiday and house of mouse market, but people are increasingly happy to book it all themselves and save money vs the all inclusive packages in recent years.
