Are there any North American airlines using garden-variety SMS to send flight updates to affected passengers?

I religiously sign up for mobile alerts with whatever airline I am flying so I can be made aware of delays. This is especially important for Torontonians like myself who use Buffalo as a starting point for our travels, a good two hours from home.

However, I have found that for the airlines I use most frequently these "mobile" alerts are in e-mail format, presumably aimed at the BlackBerry-toting masses of business travellers, of which I am not one. I have my cell service set up to send me an SMS when I get an e-mail, so when a flight is delayed, I know because my phone tells me I have an e-mail from the airline, but I have to launch my e-mail browser and download all my headers and the body of the one message I want to read, or call the airline to follow up. Nine times out of ten the e-mail body is less than 100 characters long, and could easily fit in an SMS.

That can be an expensive proposition, especially if roaming. On the other hand, incoming SMS text mesages are free for me, wherever I am.

I can't be the only one that would like a quick, short text when there is a delay, and I can't imagine it would be a hard thing to implement.

I would even pay a small fee to subscribe to a third party service, if one exists.

Thoughts?
