I’ve been through luton before and they were very friendly and helpful. You need to sound confident on the radio and think about your route. I tend to ask for a route at a certain altitude and then say … or whatever height is convenient to you.
Its mainly gonna depend on how busy they are … if you don’t ask you don’t get. Just have a backup route in mind just incase.
Most controllers are very good but they are very very busy boys and girls. I’m sure if they can get you through they will….
Have Fun
