There are some tropes that are so overused that it's pretty much impossible to use them effectively unless they are intended ironically. Recently, I read a script that used one of these and immediately tripped my "HACK ALERT." In the script, the central couple had experienced rocky times, and when the last straw came, the woman decided to pursue a job opportunity in Paris, which naturally meant she was flying out that very night.
I think you can guess where this is going - her ex-boyfriend, having realized the error of his ways is forced to race to the airport at the eleventh hour. With time ticking away as the woman is about to get on the plane he has to push his way past security, buy a ticket, and then race to the gate and deliver a big speech, winning her back.
For me, this particular gimmick passed its expiration date immediately after Not Another Teen Movie so brilliantly made fun of this sort of scene. Off the top of my head, I can't come up with where I saw this sort of scene first, but I know variations of it have been used in Love, Actually, Dawson's Creek, Three Men & a Baby.... where else? (Readers, that's your cue to comment below.) Unless the point of the scene is to make a joke of how cliched the plot twist is, steer clear of this.
And if you MUST do this, for the love of William Goldman, please don't make Paris the destination! That's about as unoriginal as you can get.
