Have any UA elites flown with Vistara under the codeshare yet? I have an upcoming 016 ticket EWR-DEL (UA), DEL-CCU (UK) in Dec and wondering if I will get any of my 1K/*G benefits like preboarding, their version of premier check-in, etc. Also I don't see any mileage charts on the UA website yet and it has been 4 months since this was announced.
