IMO before the merger Ambassador was like Global Services before the CO/UA merger...existed alongside the 1Ks (the regular Platinums), but didn't necessarily infringe upon their benefits. Happy harmony.
Post-merger, I could see Ambassador being more like new GS on the combined UA...truly play by a different set of rules, a lot of their benefits (early check-ins, suites, etc.) may come at the expense of the Plats/PPs.
I guess we will see...
