Interesting dilema I now have. My wife, infant son and I are booked on LAS-ORD-JAX. It was all mainline when I booked it. I applied a CR1 and upgraded my wife. We just had a schedule change and ORD-JAX change to a CR7. I asked a phone agent and she said both sides of a CR7 have extra masks. Is this actually the case? I figured the A side would be best b/c there was likely to be 2 masks there anyway.

Thanks.
