Actually on #2 if you make the booking for one fare on-line and then add the $50 Companion fare by phone (and do it early enough) it does work. But to use the Companion Fare you must call in. The fare the Companion Fare is the Companion of can be booked on line.
At least it did for me.</font>
Actually this is only partially true. You CAN book the reservation (not ticket) online, but it has to be a regular published fare. No Internet only fares, no internet sale discounts, and no webspecials.
