Ability to schedule and expire alerts

I like to use this site to keep track of the flights I’m going to be on to make sure that I’m running on time and that the people I’m meeting with know where I am. It would be nice to be able to schedule a start and stop for an alert. For example…

I just purchased a ticket to fly from MCI to DCA on Friday, my return trip is on Tuesday. I would like to set up my alerts to send updated information to my mobile mail for those two flights without having to find the internet to log into my account 4 times (turn on, turn off the first flight then turn on and turn off the second flight).

Time-limited alerts are planned for our next generation alert system.
