Would you be willing to switch your seats with us?

We’re a group of 4 people and and while 2 of our seats are together, 2 seats are in a different row (in the same bay) and are 4 seats apart in that row. We desperately want all 4 of us to be together.

Is it ethical to ask someone to do this for us?Would you be willing to adjust if I came up to you with this request?
