How early should I arrive in LHR for an international flight?

So I have an upcoming flight out of LHR and I have a tight schedule. It will be at 7pm on a Tuesday. If I arrive around 5pm, would it be enough time to sort check in/baggage/security? If not, how early should I arrive at the airport?

I've never had a problem leaving less than 2 hours, but I guess it depends which terminal, which airline and what time of year. I tend fo use T2, T3 and T5 and, apart from some horrendous queues for Air India, I've never encountered anything particularly untoward, even on busier days.

Thanks for the reply. I'll be flying with ANA to Tokyo so looks like terminal 2B. For the departure process in LHR, is it just check in at the counter, security, then gate, or is there another checkpoint where the officer is checking our passport/documents?

The UK doesn't have departing passport checks - that's all done electronically by airlines transmitting API data.

Two hours should be ample at T2, although you're probably unlikely to have time for a meal with a T2B departure. You'd need to allow up to 15 minutes to get between the main terminal where check-in and security are to T2B. Use the lifts either end instead of the escalators - it's much quicker, although the obvious route uses the latter.

Oh yeah I don't need to have a meal. I also have Gold with Star Alliance which hopefully help speed up the check in and boarding process. How's the security line? Someone told me it's constantly busy and can take up to 2 hours. I assume this isn't the norm?

At T2, with Star Gold which gets you fast track youll be through in under 10mins and likely faster still. Its the best terminal at LHR and the joint best Fastrack arrangement.

Would agree with the other posters than arriving 2 hours before is plenty of time.

That's definitely good to hear! Just to confirm, when you said fast track for Star Gold, do you mean the check in process or the security checkpoint (or both)?

Both. Gold Track entrance is to the right of standard security. It's not as good as it once was, but certainly nowhere near two hours!

As you have lounge access, T2B has UA (good for drinks) and SQ (good for food) within a minute of each other. AC is the poor relation in the satellite terminal.

That is the security baggage scan. Even the normal security lines do not take much time. Arriving 2 hours ahead of time I would still have time for a meal. Maybe not 3 courses.

I usually arrive 1hr45 before, check my bag (with UA but ANA would be similar), go through security, get to the B terminal and have plenty of time for a self service meal and drink (or two) before the flight.

You would be very unlucky to be in the security line at T2 for 2 hours. I am not sure what they mean by "constantly busy". Its a big, constantly busy airport so yes there will always be some sort of a Q at security. If people were frequently taking 2 hours to clear security it would not be a busy airport for very long.

I am frequently through T2 and have never been more than about 10 minutes in the security Qs, usually less.

I tutted to myself the other day when T2 fast track had a line at security that meant maybe a 7 minute wait.

When the queue at fast track builds up, they tend to open up the wall and send half of the passengers to the new generation scanners at the right hand side of standard.

I had to wait nearly 5 minutes at T2 fast track an hour ago. Disgraceful. Treating myself to a second muffin in the Senator lounge to make up for it.
