Got the same email. Kind of a good news, bad news thing. Similar to what UA does but different.
There are only 4 Global Upgrades instead of 6 SWU's. Availability on cheap fares is awesome but only good as long as there is UG inventory which has been a bit lacking.
The 8 Regionals (note this is one OR the other) will basically trump UDU's so some routes will probably be nearly impossible (think JFK transcon) without one of these.
Also wondering the position of these vs the old SWU's as far as UG.
New choice benefits? Meh, but others may appreciate them.
Hmm, wonder what they are changing for the Plat CB. Would be nice to hear from them.
