Right, so
*no advanced upgrades on Tango Plus (where you are paying hundreds more than Tango)
*cannot request your upgrade until its your "window".
When I use my SWU/CR1, I can
confrim an upgrade months/weeks in advance when I choose to pay extra for a W fare - or can confirm it on ANY fare on non-intl fares. Already upgraded an August flight HKG-GUM,HNL-IAD-YYZ with a single regional certificate on the lowest fare (K). No need to sweat and wait it out, get up early to apply eupgrades, etc.
