Not sure what business it is of mine, a passenger, if other passengers move seats, including to my row.
I'm in a row with other seats which are usually occupied. If they're unoccupied it's very rare lately. Because they're usually occupied, if someone moves to occupy them I really don't see what the difference really is.
Granted I'm plat and don't pay for MCE seats, but I am fine with FA's looking the other way. We certainly aren't "entitled" to an empty seat next to us. Those days of blocking empties next to Gold/Plats are LONG gone
