Status is intended to reward you by giving Club services to SCHs and F services to GCHs on the ground.

Once you get into the air, you will get the class of travel for which you paid. In CW a GCH may have priority for food selection if choices run out - but it will be to the CW menu, not the F menu.

If there are IRROPS status may count, but again on the ground.

As a long-serving GCH, I can say that you will not get service, food or drink from a higher cabin merely by virtue of status.

The old rule applies - pay for the.cabin you want!
