I was tense through the whole plane scene - I do suspect of June hadn't gone, Lawrence would have bottled it, particularly when it came to him being caught out and having to get on the plane himself.
Mostly though I was shouting at the screen 'behind the car is a SHIT place to hide... HIDE BETTER JUNE' as I really did think she might get caught!
I thought the scene on the plane and then the plane exploding was done really well, with the conversation between Nick and Lawrence being quite ... something.
I do think throughout each series they would have been smart to remind people via some characters looking at maps perhaps, just how big Gilead is, where everyone is and everyones going to/from, as that lack of detail did make it a bit.. flat, perhaps?
