[QUOTE=terbangalways;35088412]What specific route if you could share?
Forget about live chat and calls - reason as you mentioned.

I've ticketed few boomerangs as of mid February and all is ok.

We are trying to book

JFK to DPS through SIN
DPS to FRA through SIN
FRA to JFK

I have tried multiple ways of breaking these flights down into separate flights. It seems like the DPS to SIN route is the problem. If I take that piece out, I can book. Very strange as there are multiple DPS to SIN flights each day.
