Hello everyone, here is an additional data point for folks flying the SQ nonstop to/from New York: I flew SIN-JFK on SQ24 in the PEY Solo seat, and returned on SQ21 EWR-SIN in Business. The flights took place in January this year. Details on the seats and meal formats, as well as the EWR BA Galleries Lounge in this trip report (Link to external sqtalk.com site).

At EWR, prior to my return flight, I used the BA Galleries Lounge, but this was before BA stopped their morning EWR-LHR flight, so I don't know what the current lounge situation in EWR is for folks on the SQ flights.
