Although I don't fly much with passenger planes and I'm no "spotter" hanging around big airports, I must admit that the cockpits of airliners are among the most exciting places for me :-)

Ilyushin Il-18
Tupolev Tu-134A
Tupolev Tu-154B2
Boeing B737-500
Boeing B767-300

Il-18

The Il-18 was the most prominent - and possibly the best - 4-engine turboprop plane ever designed in the Sovietunion (although the Tupolev Tu-114 and Tu-95 was bigger and had a much bigger reach).
 

Tu-134

A small twin jet, one of the loudest airliners that still can be seen around here.

The navigator worked in the glass-nose of the plane. It must have been a great sight from there! (that's me on the picture to the left - the photo was taken at the Museum of Ferihegy Airport, Budapest)
 

Tu-154B2

One of the nicest jets of history I think! And I'm not saying this because the first plane I flew with was a Tu-154! It was slick, elegant and fast, went higher than others in its category...

Too bad that it was loud and very "kerozine-thirsty" too...

The plane had a very nice autopilot too, that was capable of doing some things that the comtemporary other jets (B-727, early B737) couldn't do. This plane was even better than its designers would thought: the soviets flew it with a crew of five (pilot, co-pilot, navigator, board engineer, radioman - or something like that), but hungarian airline MALÉV operated it with just 3 (pilot, co-pilot, engineer). And than they've made it match the ICAO-III requirements too!
 

Boeing 737-500

A much more modern aircraft than the previous ones, but also less exciting ;-)
 

Boeing 767-300

The cockpit of a MALÉV Malév B767-300. This cabin is bigger than the 737's so even I fit in there :-) Besides that, the whole thing has a certain "space shuttle" feeling!
 

Fokker 70

The mechanics call this plane "tamagotchi" I wonder why..
 

L-410

HA-LAO
