LGW-LJU in Y class. Adria Airways now offer check in on line so it was straight to security which was great. Boarding quick and efficient. Plane downgraded from CRJ9 to CRJ2 but emergency exit seat reservation honoured. Waited on the stand for 30 minutes with no communication from the flight deck. Service was nice with sandwiches hot and cold drinks. Cabin crew were quite robotic seems that pursers are trained not to smile under any circumstances. If crew would have been bit more cheerful and communication from the flight deck bit better it would have been 4*.
