AF/KL often have an agent standing at the check-in machines near where people queue to manually check-in. If an agent is there, you might find it worth having a quick word and showing the boarding pass you've printed off - they might be able to get you a "Fast lane" sticker without your having to go line up in the Business Class/Elite check-in queue? Alternatively, you might be lucky and find the C/Elite check-in queue to be short, so it might be pretty quick to get the sticker.

Its certainly worth getting the Fast Track sticker. I've travelled on early morning KL feeder flights from MAN to AMS a couple of times recently and the T2 security screening area has been packed with people.

And don't forget the AF lounge after you've done security. You'll walk through the new duty-free area, turn left when you get through that and then a left again after about 20 yards, and up some stairs. The stairs are right opposite one of the gates... 210? Anyway, easy to find, nice enough lounge.

Hope this helps for tomorrow. Have a good journey!
