By the way adam, do you keep a journal or blog of all these countries you're visiting?

Not many

Air Canada
Air Transat
United-good food
American Airlines
Ryan Air
Easy Jet
Lufthansa-awesome
British Airways-good but expensive
Caledonian Airways (do they still exist? Cause they sucked)
Canada 3000 (RIP)
China Air

Not really, but I'm considering writing a book about my journey over the past year, mainly because everyone I meet keeps telling me I have to. I'm not that into writing though...

^^^ That'll be interesting! :)

There's another 4-pages long thread on the subject here, where members rated along the airlines.

Soutwest

AirTran
Continental

Air Canada (BEST. AIRLINE. EVER.)
EasyJet
Lufthansa
WizzAir
GermanWings
AirEmerates (or something... I forget)

Okay there's prolly more but that's the gist

A short list compared to most but here we go anyway.

Air New Zealand
LAN
Jet Star
Pacific Blue

None of them are terrible and LAN was pretty awesome for international flights. All the other flights have been short and cheap so I havn't cared what they were like.

Air New Zealand has been by far my favorite(as service and what they offered).

I saw a handfull stewardess for the Emriates air carrier, they all pretty much looked like super models.

Continental
Air Canada
West Jet
Easy jet
GermanWings
Air Pacific
Air Fiji
Quantas
Air New Zealand
Virgin Blue
SAS
Alaska
Taca
United
Air Asia
Tiger Airways
Singapore
Air Canada Jazz
Pacific Coastal
Vietnam Airlines
Air Bagan

US Domestic Carriers
Northwest Airlines
Delta
American Airlines
Southwest
JetBlue
US Airways
America West

International Carriers
Air France
Air Berlin
FlyBe
BMI
Ryanair
easyJet
Scandinavian
Sabena (now defunct)

Airlines I may have flown, but can't remember for sure, are Iberia, Continental, and United. Despite the short list of US airlines, I've had my butt in a seat quite frequently. This year alone, I've flown over 35,000 miles.

Oops - add Porter to the list of International airlines.

Domestic:
ATA
US Airways
American Airlines
Jet Blue (they gave me 30 dollars off my next flight for being delayed)
United
(In general, I think all American companies suck in comparision to big European ones. When I have to fly with an American carrier overseas, I know to expect bad service, delays/cancelations, and crappy(-er) meals)

International:
Aer Lingus (wonderful and cheap)
TuiFly/Thompson
Luftansa (best flights ever, both long and short haul. if your baggage is 2 kilos over the limit, no problem, no charge, All the free booze on trans atlantic flights, and the best meals ever)
Sterling (i think that's how to spell it, it's Scandinavian)
KLM
Air Canada (I thought the plane was waaaay to old to be flying across the atlantic)
Easy Jet (shoot me now)
Ryan Air ( fav cheap airline)
BMI (Completely amazing, with a little complimentary bag of goodies for everyone!)
AirIberia (or whatever the spanish one is)

I don't keep very good track of all of my flights, so there's bound to be a few more I've forgotten.

AirTran

American
Continental
Continental Express
Delta
Eastern (for all you kids that remember it)
US Airways
NWA
Mesa Air
Southwest
United
Easy Jet

and air france, but they really suck so i guess i should not even bother to list them but there you go.

Thought I'd add mine!

Easyjet
Ryanair
Flybe
BMI
BMIbaby
Virgin Atlantic
Virgin Blue/Pacific blue
Quantas
Jet2
United
Continential
Hawaiian
American Airlines
BA

Air New Zealand has been far from my favorite (as a service and they have to offer.) I saw a handful of Emirates air carrier flight attendants, they look almost supermodel.
