First time flyers or not you have to constantly check the update departure monitors that are every 50 feet or so in the airport. Last week my original flight time was to fly out of Memphis at 9:40pm. When I landed in Memphis for that flight I noticed the departure time was changed to 10:27pm...no biggie. When I checked again at 9:50pm they had moved the flight time back to 10:05pm. If you're responsible enough to be married, you should be responsible enough to check a monitor for updates.
