I am sorry, I am definitely having a senior moment today, as I am not getting the comments I am reading on this news. Isn't there is no change at all? In fact a true enhancement where they are bring Tango eUpgrade-able as a permanent option now. Booking classes "S, T, L, A, K" are Tango, isn't it?
All it seems AC is doing is free up or eliminate "Tango" and combine it in Flex. Isn't that is a comment many had made in the past on why keeping this name?
Whether they will recycle Tango to make it the UA Basic Economy fare, or come up with a new name, that I am not sure.
There is now a copay for domestic travel eUps even for SE. That is new. If you look at the table, the copay is greater for Tango, but there is still a copay for Flex.
