well there will be an extra a/c in the first rush at 5am (z) which will indeed mean more queues on a monday morning and more delays due inept de-icing in the winter (if they last that long) and then ourmain rush periods are 0830 1000 1400 1700 and 1900 so 2 extra a/c at 0930 one at 1100 1255 etc shouldnt cause too much hassle might just be at 0600 and 1700 that we have a problem but with the extra staff it should be just about bearable!
