So far night flight still very zhun...and I'm talking about SQ
nia..
SQ 11 never fail you night guys so far..and is always full
loaded..
hmm.... nite muz see which terminal lor...... like T2 yes major
flight is 981 n 835 but
muz monitor cause sometime 835 will land at T3 like ydae
nite......... then sometimes
delay like tat day sunday but seldom happen. for T3 is 15 liao
but plus UA117 n 881
so SQ not major player in T3, then for T1 is all the other
flights cause SQ dun operate
there main course is DL621, for midnite quite systematic which
terminal to go at which
timing. for me after 6mths trainned by limo group can say almost
master liao...... 
as long u r infront of me at any terminal u sure go out very
fast 1...................
