JetBlue TrueBlue - B6-US fares

itasoftware.com gives me a very attractive fare from IAD-SFO, one-way outbound (nonstop) on B6 and one-way return (connecting) on US. However, I can't seem to find an internet site that will book it. Is there a compatibility problem in booking such a ticket on these airlines?

If you are seeing it listed that way on ITA then it is probably because you can buy it as two different one-way trips. Just price out one way on US and one way on B6 and your total cost should be the same.

If you have two browser windows open you can make sure that both are available at the prices that they should be.

That's it; thanks! Should have figured that one out myself --
