Certainly with the known fleet plans Delta will be able to reduce our number of departures to Europe using EASK. During that time we will replace most of our 218 seat 767's with 287 seat A330's and some 320 seat A350's. If the 777 rumor turns into reality we may see more of those in the transatlantic market.
The situation with AF/KLM is fluid because they are in deep trouble. Their current plans are to downsize aircraft size however they may now cancel the 787 order. They are however in deep trouble. I hope RA has a plan B for European feed in the event it all collapses.
