make sure you read the prospectus carefully before deciding to buy. The airline biz is a difficult one to invest in, usually because of the uncertainty over fuel prices, cyclicality, and the issue of labor unions. No unions to worry about in JetBlue's case. And IMO, they are not as subject to the cyclicality because they are adding routes that are popular with their clientele. I'd also check their load factors for newer cities versus existing cities. That should tell you how they are doing on the growth track. Similar to looking at same store sales of Wal-Mart versus new store sales.

What you have to do is make sure the stock is fairly priced according to other airline companies (Southwest, Skywest, RyanAir and the other Europe based start ups, etc. - not AMR, UAL, DAL, CAL, NWAC) and also make your judgement as to the competency of the management team to execute the growth strategy that has gotten them to this point to date.
