Here are the glitches I experienced yesterday:

+ Search by Price had the inbound and outbound segments I wanted, but not as a pair.
+ The first time I chose Search by Schedule, I got an error message.
+ At one point, one option had a ridiculous price, something like $1453219.
+ When I was able to choose the segments I wanted (by Schedule), they changed eached time I tried to purchase the tickets.

Finally, I gave up and booked through Orbitz.
