It should come as no surprise that airline travel costs are increasing. The bad news is that it is virtually impossible to figure out what airlines charge for their various new fees while you are buying tickets without spending hours researching. Recently when I went down to ITEXPO, I used American Airlines to fly down and JetBlue to get back. AA charged me for curbside check-in while JetBlue did not.
So there seem to be absolutely no standards in terms of these added fees.
I expected WiFi on the JetBlue plane but found out only one plane in the fleet has WiFi access according to thew in-flight hostess.
