The 773 is doubtful that are gonna be 10 by the end of the year. But it's 100% that 4 772 will be faced out in December or earlier plus another 2 until February.So the real gain will be 4 frames but keep in mind that further 772 will go for sunbathing somewhere inside OEJN.So there will be no real gain in B777 frames. Furthermore Expect a delay in the 320 NEOS as Airbus is facing huge delays with the engines of the aircraft
