3. Even though we may ask for up to 20 flights to be displayed by schedule, we often have to know flight time and enter it to get certain flights to show up. A search by schedule should show all flights available.
Agree with the second comment.
The multi-city ground travel segment thing is the only way to ensure that the system prices everything as one itinerary, rather than separate itineraries. It may be a nuisance, but it's really just a question of getting used to it (and remembering to switch back to air travel for subsequent inputted segments!).
In its favor, ual.com is the only site I've encountered so far (I expect there are others) which allows you to book open-jaw itineraries online rather than having to phone.
