I flew a couple of segments on TAP, The Air Portugal, for the first time, as United Airlines Premier Silver, which gives Star Alliance Silver status.

I was surprised to learn that TAP gives the Economy Plus benefit at check-in for free for Silvers. Got it on both of my flights: first time through the gate agent and the second time through airport kiosk.

The only benefits I was expecting were Priority reservations waitlisting and Priority airport standby. I guess, there are more.
