Yes, I agree that Northwest is not the best airline out there,
but they do offer the most convenient routing from the Twin Cities
to Singapore, i.e., MSP-NRT-SIN.
The only drawback is that the flight gets into Changi at around 1
a.m., and departs at around 7 a.m.
Their fares are also relatively reasonable. If I book a flight
early enough during the off-peak travel season, I can usually
secure a return ticket for a little under US$1000. In addition,
each flight is long enough to yield sufficient FF miles for a free
domestic ticket.
Of course, with Northwest in Chapter 11 now, it's anyone's guess as
to what will happen to them in the long term.
