Have been holding seat 22A on a 321 on the basis that it's emergency exit and there's no seat shown in front - I don't know whether there really is no seat or there is just not one shown on the seat plan (as sometimes happens).

Now 3 days before departure, only 4 rows are taken with club so the forward emergency exit row has become available, row 8.

While its unlikely that club will expand to fill 3 more rows I wonder whether if the flight is lightly booked they will prefer passengers to sit towards the back so these rows could be closed off again ?

Is it worth moving forward or better to stick with more room further back ?
