Reservation system that displays fare basis availability
Where can I find a reservation system (preferably on the web) that displays fare basis availability (e.g. F availability = 3, Y availability = 7, B availability = 3, V availability = 1, etc.)? EasySabre and ITN used to support this, but EasySabre is extinct, and ITN seems to have eliminated the "expert" mode that provided such information. Thanks for any help!
