This change actually made me feel better about not earning my RA status back. The chasm between RA and Ambassador is shrinking. Especially for those of us who have free diamond breakfast and free two year lounge pass.
We only arrived pre 10am once in 2023, that was our holibobs at IC Buenos Aires. We were shown to the suite right away. Also I have looked back on our upgrades received last year and some of them were five or six levels. IC London PL only gave a two level upgrade. This was the least generous in terms of levels.
I think the best RA benefit is no daily amenity fee for those who travel stateside.
