May attention, shoppers?

13. Why is the announcement being made?

(92) This is an important announcement for anyone waiting to board Flight 321 to Montreal. Due to the cold temperatures, some extra maintenance is being carried out on the aircraft's engines. (93) This will result in a delay of around 45 minutes. We do not anticipate any further delays to this flight. Please be ready to board the aircraft from Gate 17. Boarding will commence at approximately 7:45 p.m. and (94 )the new departure time will be 8:15. We apologize for this inconvenience. Please speak with an airline employee at your departure gate if you have any questions. Thank you.

Hello, Ms. Gardiner. This is Anthony Costas calling from Europa Travel Agency. (98) As you requested, I changed the date of your Zeus Airlines flight. (99) You'll be taking the flight that departs at 11:35 A.M., instead of the one that leaves at 4:55 PM. Your ticket is still for economy class, and the same baggage allowance applies. You can print your ticket at the airport by using the self- service check-in booths in the departure terminal. (100) However, I'd recommend just checking in on the Zeus Airlines Web site 24 hours before your flight. It's a very quick and convenient process. I hope you have a safe flight and an enjoyable vacation.
