Last night I created a flight alert for my AA flight home this afternoon, electing for text messages to be sent to me phone. In this middle of the night (around 3 AM), I got a spam text message. Then another around 7 AM today. Just now 2 more have come in. Coincidence? Prior to this, the only other time I got spam text was about a month ago, about 4-5 messages within one day, immediately after setting up another flight alert.

I use flight alerts all the time, typically no problems with spam. I don't do any other texting at all, just flight alerts.

Has anyone else seen this pattern?
