look, sometimes BA can take a while to get back to you - don't get paranoid about this.
IT'S NORMAL.
good luck to all of you.
and if you get offered LHR over LGW - TAKE IT.
LGW is supposed to be a fantastic base to work out of - the crew are supposed to be a scream, but you will get ALOT more money at LHR and be INFINITELY more secure in your job at LHR. the agreements are ALOT more restrictive and PROTECTIVE at LHR.
again, good luck boys and girls!
