Now that it is available worldwide I have upgraded to Tripit Pro.

It saved me from missing a flight earlier this week. I was on a delayed BA flight from LHR-EDI and got the SMS with the delay sent to me. I checked the board and the delay was the same. Fine, I'll sit in the Galleries South a little longer and have a couple of extra glasses of champagne

An hour later I got a another SMS saying PULLED IN. The delay had been reduced by 30 minutes and the flight was just about to board. The screen had been updated but I was sat in my own little world reading a book and having a few drinks.

If I hadn't got the text I would have missed the flight (my fault I know - but delays getting shorter is unheard of with BA at LHR!!) and the last flight home was full.
