I wouldn't advise you to buy airline stock right now, save for jet blue or southwest, maybe.
I just sold my 165 shares of UAL for a paltry sum...about $65 I believe. I purchased the stock after 9/11 for $500 and it briefly rose to about $1500 at its highest point during my ownership. I decided to cut my losses and walk off with $65 rather than wait for the stock to be liquidated under ch. 11 and walk away with nothing.
Go to Cnn.com or Yahoo.com for stock quotes. Most major sites have ticker symbol lookups if you are unsure what the symbol is.
Here's a few I know of the top off my head and check regularly:
Jet Blue: JBLU
British Airways: BAB
America West: AWA
Remember, these are all traded on NYSE
...there are other airlines which trade over the counter, but I don't know their tickers since I don't track them.
I love America. I guess that makes me Bush's poodle, but I'd rather be a dog in New York City than a prince in Riyadh.
