Can someone comment on what expected service is on SFO-SIN, in Y. I assume at least a 'full' meal after take off, another 'full' meal a couple of hours prior to landing, and something in-between - would it be similar to the mid-flight small sandwich I got on SFO-LHR, or something somewhat more substantial. Also, are there any differences between the services departing morning and evening - ie, would UA1 get breakfast prior to arrival since it lands in the morning, vs. dinner on UA29 since it lands in evening? Or are meals pretty much the same?
