As I described in a previous entry, the movie will start with our protagonist getting bumped off her flight home after a particularly bad 3-day trip. This causes her much frustration and incites in her the desire for change. It also leads her to start a blog. (BTW, I watched Bridget Joneses' Diary yesterday and realized that it begins very similarly to this.)
Elena (our protagonist) starts thinking about a change of path, but doesn't take action until the first turning point: Legacy Airlines announces plans to layoff several thousand flight attendants. Fearing she will be affected, Elena goes in search of another career (and ASAP!)
Act Two consists of Elena struggling to find a new career, but instead only finding dead ends and disappointments. She's relieved to find out afterward that she will, in fact, not be affected by the layoffs. In the meantime she has realized being a flight attendant isn't so bad after all. Surely all the perks are worth the occasional frustrations, right?
Also in Act Two, our heroine finds romance on a layover and starts a long distance relationship. She thinks this will work out better than dating someone back home, since she's never there anyway. I won't disclose the conclusion of this subplot.
There will be another subplot about a "Long-Suffering Frequent Flier," which will conclude here.
The second turning point will be: SURPRISE! Just when things are going smoothly, Elena is fired from her job because of her blog and decides to sue Legacy (her airline). A publicity blitz ensues (and our heroine, like Bridget Jones, is a horrendous public speaker) and then the Climax and Resolution, which I'm not gonna disclose here either.
P.S. I forgot to mention the tone of the movie will be similar to Bridget Joneses Diary (a comedy) with some Scrubs-style absurd fantasies/flashbacks.
