Tip of the day!
It is always worth to give a call!
I was looking for a while to snag a flight on Swiss YUL-ZRH-TLV, there was availability on the YUL-ZRH portion for the day I wanted, but there wasn't any availability on the leg from ZRH-TLV on the morning flight (I didn't want my wife to hang around for 16 hours in Zurich....(it would be too expensive
, so my wife called up United, and they were able to book it, even though it didn't show up neither on United or AC, (ANA sucks anyway... since they ''''updated'''' their website).
