So. KLM. Royal Dutch Airlines. You wouldn't have guessed it. Well, you might. But anyway, on with the op.

(Please Note: Due to the fact I am in fact 14, and, obviously, did not pay for the holiday, I am unable to tell you the full price of the flights. Sorry...)

So there we were, checked in at Newcastle, in the waiting lounge, staring out at the dull-looking plane that would carry us several thousand feet into the air, before pulling us down into the land of floods, cheese, and people in funny clothes. Someone in the room said 'It's nice to see people on a plane again'. And they were right. In the weeks between this day and September 11, people had deserted aircraft altogether in fear.
Once boarded on the plane, the pilot entertained everyone with his speech (well, not exactly 'entertained') before we took of for the runway. I noted how uncomfy the seats were, and the lack of, well, anything. A single, battered-looking magazine lay in the pocket on the back of the seat, wearing a look that said 'Please read me. Please...'(Yes I know it was a magazine, but it still wore a look!). I couldn't resist having a look. Inside was a brief note from Mr Edwin-Van-Der-Something Dutch, chairman of KLM, and a load of useless information that could only interest two kinds of people; financial and aviation enthusiasts.
After a vicious looking Dutch woman came along wielding a trolley, and threatened us to buy something. I asked for a cup of coffee, but quickly changed my mind for a glass of orange juice. When I suggested this, the woman seemed to scan her eagle-like eyes over the trolley as if looking for something to hit me with, but then chose to pour me a glass of orange juice bitterly. The orange juice tasted a bit crap, but I also got this strange caramel biscuit thing, which was delicious! That was the best part of the flight!

Soon though, we had to get to the lounge, where we sat down. But, things weren't going right. After a while, they announced we couldn't board the plane because 'it was too hot'. This story seemed to continue, but get progressively worse. By the final announcement (an hour later) the plane's air conditioning seemed to be bust. But after various complaints, they let us on the plane, the air-conditioning suddenly fixed.
It was now dark, and we sat down in our seats onboard the Boeing 747. I was extremely disappointed to note the lack of back-seat television screens, instead there was just one small one every few aisles above the seats. That was bad. All the other entertainment consisted of a poor quality selection of radio channels. Yes. Now I've been on a few airlines now, and I have to say Air 2000 offered a fantastic selection of radio channels, including all time classics, latest releases and, a comedy channel. I felt glad that I had a Walkman, a Gameboy Advance and a book. (Make sure you do exactly what I did if you go on KLM) After a while they put Moulin Rouge on for our 'enjoyment'. Now I no I'm certainly not here to rate that film but it was AWFUL! Imagine being forced to watch a crap film, with good actors, because there was nothing else to do! (My books, Gameboy and Walkman had lost their novelty by now). Every so often a woman (nice one, this time as well) and offered things. I went after some more of those scrumptious caramel biscuits again...in fact; I bought a packet at Amsterdam on the way back, they lasted around 3 hours! :) )
Return flights were pretty uneventful. they put on 'A Knight's Tale' and believe me, the title says it all. Also, please note, JFK is a horrible place.
So anyway, enough about me. I imagine you'll be wanting some interesting information?
The seating are about as basic as you can get. Not comfort at all. They give you a handy 'blanket' (or in reality a smelly old rag) and a 'pillow' (a very worn out one as well)
They do give you a decent selection of food, though, and with the constant time changes, this can be very disorientating. Like early in the morning, Eastern Seaboard time, (but it felt like midnight to us) they came around (it was still dark outside) with a bright yellow breakfast box, reading 'Good Morning, here's your fresh breakfast'. That was very weird. (Note: it wasn't a particularly fresh breakfast either)
Staff are (mostly) friendly, both onboard, and on the ground. They will get you something if you need it, help you, etc. Definitely a good point.
But the comforts are basic. And I mean basic. Obviously, its not like you're loaded onto a bi-plane with some straw, but they hardly do anything to be nice to you. That includes the magazines. There's little legroom, and it's pretty darn hot up there.
From what I remember, prices are average, nothing cheap, and nothing amazingly expensive.
