plane ride to Paris

I had a dream last night that my wife and I were flying to Paris. Sounds
great, but in the dream we never leave the airport. It
was one of those anxious dreams where you never accomplish the menial
tasks of, in this case, boarding an airplane. In the dream I have
trouble with the TSA people, which isn't exactly fantasy. Ever since the
ramp-up in security, I've been on their watch-list. Not me specifically
but rather my name is apparently a cause for alarm. If this happens to
you, you should know that there is a form on the TSA site that can
remove you from said list. I never knew it existed until it was
mentioned to me rather casually by a check-in agent. You can get that
form here if you're in the same boat and afraid you'll miss your plane.
Anyway, this uninteresting dream lead me to a new brainteaser which I'm
not sure is solvable. Here goes...
You're lucky enough to get a first class window seat on a transatlantic
flight, but your (wife, husband, friend, etc.) is stuck in a middle seat
in coach. You'd like to sit with them but you can't get over the fact
that you'd have to give up such a great seat. You happen to know that
there are a few empty middle seats in coach, so you'd ideally move back
to coach to join your friend so long as the two of you can have that
extra seat in your row to stretch out in. What's the minimum number of
moves of people you can make to arrange this (if it's even possible)?
Understand that you can move people, or rather convince people to move
only if they get a better seat.
1. first class is preferred to coach
2. window seats are preferred to aisle seats
3. aisle seats are preferred to middle seats
4. and sitting next to an empty seat is preferred to sitting next to
people.

Make sense? Is there a solution?
