Hello. Passengers of flight 17 bound for Caracas, with stops in Atlanta and Miami. The departure gate has been changed to 30B. Also, there will be a slight departure delay due to inclement weather outside. The ground crew is in the process of deicing the wings in preparation for departure. It also looks like the flight is slightly overbooked, so we are offering complimentary round-trip tickets to a few passengers willing to take a later flight. We should be boarding about a quarter to the hour. Thank you for your patience.
