We've got row 7A&C seats booked on our upcoming 4hr flight, the middle seat is blocked off and we always use it to put our DS(nearly 2) in after take-off and before landing.
We often get the first row and it really makes a massive difference when travelling with DS: the extra space at the bulkhead is invaluable for him, and to keep him contained to not bother other passengers.
We didn't manage to book early enough this time, however according to the seat map 1C&F are empty (usually just blocked for the comfort of the Gold member seated in the other seat), these usually open up just before the flight.
So: am I being unreasonable to move us to the empty seats in the front row and hope/expect 1A or 1D to move so that we can sit together? They'll still have their aisle/window and won't have to sit next to a baby, so I think it's win-win..
Not to drip feed, I'm also 5 months pregnant, so anything to make things more comfortable really.
YABU: Stay in you're current seats and let the fancy Gold members keep the empty seat next to them!
YANBU: It doesn't make any difference to them and will make your journey more comfortable (and probably everyone elses as DS will have more room to be contained)
