Highfive; I don't really understand. You write that no one got a LGW contract so far? About 150 Norwegian B787 pilots are on a LGW contract. The rest of them in BKK.
After three years you'll get offered a permanent contract with OSM Aviation.
It has been discussed here before if you must do the online tests twice. I suggest you read the invitation more careful where it should clearly say that if you have done the tests within a year you don't have to do them again. Quite simple.
