Successfully requested release on an extra U award on an E190 - 2 March ADL-BNE. Was already 1 U, but needed two. Was showing J9 C9, D9, I7 (so no J bookings at all) and the second U was released. Now showing J7, C7, D7, I5. Is the 20:40 departure, but is a Sunday evening.
Fares on this route are crazy as well J is ridiculous at $700 one way, but unless taking the real red-eye (only $249 in Y), the Y fares are either "cheap" at $349 or $409 one way, It was those Y fares that pushed me to forking out the points for U class - could redeem U one way, and pay revenue the other way in J, and basically the same cost as revenue Y return (and add a DSC on the paid fare, and a positive status outcome as well).
