STN is not bad for spotting. I used to live in Bishops Stortford.
You can sit on the grassy knoll outside the departures terminal and you get a decent view over the terminal roof and the monorail, but you'll be properly big time sick of Ryanair 737s after an hour. I believe their DREAMLINER liveried 738 is based there although I've never seen it personally, so if you are the spottery type who looks out for these things then its something to look forward to i guess. 90% of it is Ryanair or Easyjet A319s. Norwegian and Germanwings send 733s and A319s, and Air Berlin send A320s, 73Gs, and I've seen their F100 there once too. Are Wizzair still operating? If so you'll see their rather fetching purple A320s, and that Czech LoCo i can never remember the name of send 737s too. There are the odd charter bird, mainly A320s, from Monarch, First Choice and I think Thomsonfly as well. You see the odd Aer Arran ATR as well.
Interesting stuff is generally cargo - UPS 767s, FedEx MD11s are the highlight, although the EOS and El Al 752s and AA
763ER make a welcome change from the drudgery. There are always the wetleased 744Fs that BA
Cargo use on the cargo ramp, and i've seen Korean Air Cargo 747s there too. TNT send the 733QC I think.
There was talk of PIA sending A310s to STN
this Summer, and AA
going double daily, so probably they'll bring the 757 for that.
What do you mean you dont have any bourbon? Do you know how far it is to Houston? What kind of airline is this???
