Our first time flying Emerites. Economy tickets for two senior-ish citizens. We have a preference to sit as far forward as possible, but not in the rows that tend to have small children. DH likes window seats, forcing me to sit in the middle.

1. How many flight attendants are usually on this plane and what is the approximate number in each of the three classes of service?

2. BOS-DBX Boeing 777-300ER. We have seats 19K and 19J. Comments?

3. After 3.5 days in Dubai, we are on to Cape Town, Emerites also Boeing 777-300ER. We have seats 28A and 28B. Comments?

4. Return flights are the same type planes. CPT-DBX seats 28K, 28J. DBX-BOS seats 20A, 20B. Comments?

If you don't mind being last off the plane, get one of the seat pairs at the very back of the 777, where the layout becomes 2-4-2. Rows 46 to 48, seats A/B and J/K are good if they're available (row 46 feels quite roomy, but the armrest is immovable). You'll feel much less hemmed in here than if you were squished between your SO and a stranger.

If you want to get up and walk around / go to the bathroom frequently, I wouldn't recommend getting A/B or J/K seats in any other rows. Better to get D/E or F/G seats.

If your SO won't budge on getting a window seat, and the paired seats aren't available, I suggest getting an A/C or H/K pair close to the rear of the aircraft. The rear fills up last, so you may have an empty middle seat. If that seat is indeed taken and you want to sit next to your SO, I'm sure your neighbour will be more than happy to switch to the aisle seat.

Don't get the first one of the pairs because the screen isn't aligned with your seat.

Your seats seem fine not too close to the children seats whilst still in front although if you move to above 20 on your cape town seats you will be more front

As for number of Crew it is usually 7 plus one senior
