Yes, complain by all means but don't expect any recompense. I find it disgraceful that points upgrades to business PER MEL are the same for the A330 or 787 genuine business suites vs the very ordinary “business” seats on the ageing 737, which are not even up to the 787 premium eco in my opinion, ...

None of the 717 routes I fly (mainly PER KTA) has business. For non business flyers unless you are lucky enough to get row 4 in the 737, the 717 is in my experience gererally quieter and more comfortable (though the back rows sound pretty noisy when one ventures there.)

My understanding from a very senior training captain in a leading airline is that there is zero risk.What would concern me would be having multiple loudmouths having conversations throughout the flight.
