My birthday was in August, and definitely didn’t get one of these - would have been nice to use on the SFO-SIN flights I had in summer. I think at some point earlier this year, I did get some % off E+ offer emailed, but can’t remember if that was for my birthday, or something else.

just curious if this is valid for birthday pax only, or also for those traveling with them on same PNR?

on another note, I flew TG on my actual birthday, and no recognition at all (though I wasn’t really expecting anything). Then checked in to Shangri-La Singapore after arriving, and despite not telling them anything except giving them the pre-arrival info. they asked for, got a card to check the fridge - there was a 6-inch Happy Birthday chocolate cake from their in-house bakery - was pretty darn good too.
