SMS trend for travel updates

More airports, airlines and trains are setting up text messaging services to keep travelers updated on the state of play on flights, travel times and bookings.
The British Airport Authority (BAA) has launched an SMS service called "Flying Messenger" for passengers who are catching a plane or meeting colleagues at London's Heathrow or Gatwick airports. This allows people to check flight departure or arrival times when they text their flight number to 82222. Texts are charged at 50 cents per request. The service provides flight details from 12 hours before departure, as well as up to four hours after arrival.
P.s. CNN’s quick online vote results to the question ‘Have you used text messaging to request travel advice?’ : 0% have texted to request travel advice! Is this a trend or what? I must admit the vote is irrelevant. Only Internet users who have chosen to participate have clicked on the yes or no button. Did you know that at Jakarta's airport you can even request , uh, toilet paper via SMS. Hmmm, what's next? Demanding airport toilet updates by sms?
