It's that stupid scam that starts with a boat horn and has some guy saying "this is your captain speaking..." and some crap about doing a survey for free boarding passes. The survey is automated and it tells you to press 1 or 2 for your answers. I just kept pressing the * button and apparenlty that was sufficient because it said I completed to survey and to press 1 to get my boarding passes. The message assures you that you won't be prompted to give your credit card information, only your first and last name.
Upon pressing one some guy in a grumbled most likely not English accent answers and says only "first and last name?". I just pressed the number keys in his ear until he hung up. I'm so sick of getting bothered at work by these fools!
