Just trying to help you guys improve things.
At KSBP you can show all scheduled airline flights as using gate 1 and baggage claim 1, since that is all there is.

Thanks, John. 
I know you can find the tail number on the flight status page for Continental so I’m sure Continental will be an airlne shown with the registration. What other airlines do you plan on having tail numbers for?
Well, availability on the web doesn’t always result in an available data source. Fortunately, they are on the list, though – United, Delta, Continental, Frontier, Air Canada, Thai, El Al, Singapore, Air New Zealand, SAS, ANA…and some smaller carriers. More coming all the time.
Just curious, any plans to add the (track inbound flight) feature for American Airlines?
Yes, but it won’t be in the near future.
