I found this itinerary ITA Matrix:
However, I am having trouble booking it online. I've used aggregators Kayak and Hipmunk. Both display the itinerary but they show a much higher price.
Is there a place online where I can book this itinerary?
Alternatively, is there any travel agent I can call and have them book it?
I've read some other posts where users suggested to change the sales city, but my sales city is the same for all searches (Boston).
