Camila Mendes is Ana, originally from Florida and, with an art degree, is a lowly assistant in a big name New York auction house. She is pretty broke, she sleeps on the futon in a very small apartment her sister shares with her boyfriend. On this fateful day her boss calls, she is told to go with them to London. Right now! There is a big art collection that needs to be auctioned off.
Ana is given an unexpected gift at the airport check-in, the agent sees how badly her catty co-workers were treating her so gives her an upgrade to first class. Thus the name of the movie.
In first class she sits next to a nice young British man and in the conversation she says something that leads him to believe she is the head of the auction house and she doesn't correct him. After all they don't know each other, she will probably never see him again and it felt good to feel important. But as the story develops it works out way differently.
Marisa Tomei is Claire, Ana's hard-driving boss, who speaks and sounds just like Celine Dione.
I like Tomei, she is good in everything, and I became a Mendes fan for her role as Veronica in the TV series 'Riverdale.' The two other assistants to Claire are overly annoying bullies in the workplace, a bit over the top I found, but otherwise it is a very well put together movie.
My wife and I enjoyed it, streaming on Amazon Prime, after our usual Saturday evening steak and wine dinner. With chocolate cake, of course!
