EG extra luggage allowance in Y to US (linear dimension)

[Danny Bhoy]

EG/PPS/*G extra baggage allowance to US is 1 extra piece (max 23kg).

But in the case of Y travel (to US), given that non-elites have the max 273cm/107 inches total linear dimensions for 2 pieces, what is the max legal size for the extra luggage piece of elites? 158cm/62 inches?

Hope you don't mind me piggy-backing onto your question.

Was actually perusing that luggage restriction page on the SQ site a few days ago (I wanted to bring back a bean bag, but not sure if that'll fit)... I got the impression it'd be 2x 158cm / 62 inches for elites, although I also do recall 40kg being mentioned somewhere...

If the experts could step in, thanks
