That would be a foolish game to play. From recent experience of 2 or 3 airline interviews, I was given maximum 5 days notice of the interview date. There was no conceivable way of getting an MCC done in that period of time.
Your going to look like a complete prat(and a liar!) having to confess "ah well...um....i dont actually have my mcc yet, even though it says so on my cv"!!
You will blow your chances clean out of the water and certainly wont be asked back.
Best advice - get it done! If your going for the airlines then you need to do it. Get the ticks in the boxes and you wont have to worry about it.
