More things Full Dislosure Airlines will tell you:

"Before pushback you will hear things go 'ping' in the cabin a good 10-15 times, for no discernable reason. Also, prior to landing we will show you a professionally edited video about the arrival airport... That will be of no value to you whatsoever, as it was recorded 3 years ago, prior to the airport's radical grounds-up refurbishment. (unless we show you one of the wrong airport)"
