Oh and ATC could you please remind us 30sec after we've been cleared to 7000 to "maintain 7000" and also after we've been cleared to 9000 I'd like to hear it again, actually could you do it all the way to the FIR it's really helpful.
Could have helped over Europe one day when traffic below, cleared to FL320, continued the climb. We were at FL330 right above him. I didn't wait for TCAS; I went, and was then told off by chief pilot for failing to wait for TCAS.
I, in response, advised that I was PIC and dealt with the conflict as I saw fit. No further action.
