The Open Skies agreement allows any European airline to fly point to point without flying through its own country. Today I took the BA service (yes, I am a mileage slave) from Paris to London. A tricked out 757 with flat beds in a small cabin feelsfor all the world like a private jet and was quite wonderful despite the slightly outdate IFE system. But no matter, it was a fine experience.
Open Skies should be excellent news for the business traveller, you get to fly on the airline that treats you right because of your status, you get on smaller aircraft with quicker boarding and deplaning, you get your entertainment in your own language and, in BA’s case you get to avoid Heathrow!
