Cons:I Booked a flight that stated that it only had one stop in singapore, then direct to SFO after arriving in singapore i was told that i had to go to a transfer counter, that there was a problem with my ticket. after arriving at the transfer counter they took my boarding pass for my dircet flight to SFO, & told me that i now had a stop in hong kong, that the direct flight to SFO was over booked!! this is not right i wouldn't of booked this flight if they had been truthfull about the extra stop. i will never use singapore airline or kayak again!!!
