I’m platinum with KLM and frequently use the E-Jets. I have a routine to ensure this doesn’t happen and simply it’s be there early.
At NCL, you can work out the gate before it’s called and be outside the door before the masses leave the lounge or the pub. Same on return at D6.
If they are looking at trolleys in the hold, that is when the flights are full (probably not going to be full now) and generally they don’t take them off business class passengers or platinum.
So, no guarantees but you can get round it with a bit of planning.
And to be honest, a full 737 is just as bad, if not worse than an E Jet where I often see gate staff asking for volunteers to gate drop their bag.
