American Air says it will spend $2 billion to upgrade planes; Delta to tweak top economy seats

American Airlines says it will spend more than $2 billion to make its planes more pleasant for passengers, the latest salvo in a competition among carriers to attract high-paying frequent fliers.

Rival Delta is breaking its two-cabin service into five levels and giving a few goodies to economy-class customers who pay more than the cheapest fares.

American Airlines Group Inc. said Monday that it will invest in lie-flat seats, Wi-Fi service on international flights, more entertainment offerings and a refresh of its airport lounges around the world.

CEO Doug Parker says that with the expanded global network created by American's merger with US Airways, it now plans to deliver a better product than competitors.
