How long to arrive before Easyjet flight?

Is 1hour cutting it too fine?

Domestic or international?

Don't think it matters between domestic or international. You don't need to go through passport control.

Depends more on whether you have luggage to check in, but I generally get there 2 hours before at least whether or not I have luggage.

Of course you do if it is international.

In the UK you do not need to show a passport to border staff to leave the country. This is in contrast to most European countries where you do if you are leaving the Schengen area. Here it is just usually the policy of airlines that you show them it before you board to 1) function as ID and 2) ensure you have the correct document for passport control on arrival. You'd need to show them ID before a domestic flight anyway.

I'm sorry but this isn't strictly true, what if someone was using an expired passport or had no documents at all, they could just get on a flight even if they are barred. Stop speaking rubbish.

What are you talking about? you need passport to show your passport to leave the country via plane. Domestic may not on very short flights or obscure routes like , EXETER TO LONDON CITY AIRPORT.

Neither of you have refuted what I've just said. I said you do not need to show your passport to border staff. There is no passport control counter for exiting. You need to produce ID (whether it's a passport, national identity card or the like) valid for entry to the port of destination to airline staff at the boarding gate prior to departure - that is to minimise the airline's potential liability should you be refused entry to the destination port. It is purely airline policy and not government policy. My original point was that as everyone has to show ID to board an aircraft in the UK, but at the boarding gate only - there is no inherent value in getting to the airport earlier for that reason.

The only reason I can think of for arriving for an international flight earlier than a domestic one is that the latter is likelier to be departing from a smaller airport - and even then, BA has a number of domestic departures from Heathrow.

All these idiots not actually answering the question.

Yes, an hour is fine. But obviously consider traffic / public transport delays.

You clearly have never flown before. You need to be there at least 3 hours before.

I fly 2-3 times per month. (works out to 4-6 times as a return)

3 hours??? You are wasting so much time. If I was checking in luggage or flying very long distance I'd get there slightly earlier but for a European flight an hour is more than enough time.

Join the club.

International, the check in closes 40 mins before the flight itself.

1) Check-in online. Unless you need to check in luggage you don't need to go to the desk. If you are flying just around Europe you really don't need luggage.
2) If you meant the gate closes 40 mins before the flight, you're right. That leaves 20 mins to get through security - about right.
3) Gates never actually close at that time. If you get there at the time specified there will always be a long queue of tickets/passports being checked.

Out of curiosity, how does an A-Level student find time to fly multiple times a month?

Very wealthy, lots of weekend trips, plus lived abroad

Well I'll give you a tip. Next time you catch a plane, only go an hour early and see if you make it. If you don't, you won't miss the money anyway.
