Routing Options for Reward Travel
I have always been confused as to how to determine all the different routing possibilities that are allowed.
I'm trying to plan a reward booking and want figure out routing options to include a good layover/stopover.
For example, if I want to fly from EWR to CDG am I allowed a stopover in any other European city as long as there is a *Alliance flight from that city to CDG?
In general what rules govern if you are allowed to book either a layover/stopover along the route? I always see people here discuss complex routes, but it confuses me as to why they would let you bounce from city to city if there is a direct/cheaper route available. I'm pretty new to this, thanks in advance
