No bag to check in - how long before flight would you arrive?

Not checking in any bags so only need to go through security and to gate for flight. How long before flight would you arrive?

Exactly this. I've flown out of Bristol a few times over the last couple of months - mid week, afternoon or late morning flights were no problem, I flew through. However, Friday early morning (7am flight), and there were around 17 flights within an hour of mine - there were substantial queues. Look at other flight times leaving around the same as you.

But I would generally bargain on 2 hrs.
