I dont see the value prop of sq's premium econ.. especially with its current price point. They make no efforts to differentiate from competitors. Tried it once and wasnt impressed.
i used to travel beween asia/singapore and us west coast. BR pe was a superior choice , one thing that differentiated was eva's dedicated lavatories for PE passengers.
sq pe lavatories is mixed together w econ section and its all the way at the back.
Granted theres a transit at TPE, but its still managable with its price point and occassionally allows me for stopovers at tpe for other matters.

Nh pe is also competitive with its lounge access for PE pax.

Sq pe has BTC but the problem is that they heat up your btc very early on, and serve it to you without any drink services. Drinks only come along when the normal meal carts arrive, and by then ur food would be cold, or ur food would be consumed by then. The price of pe is also equivalent to some other carriers business class, which again does not make sense. Example i did Cathay business to tokyo recently with prices that was the same as sq PE. The nicer seat plus lounge access in hkg didnt make my transit any pain.

Didnt meant to rant lol but i think it goes to show our point on sq Pe lol
