sorry I didn't reply to your question sooner.
I rang the normal booking number and said I wanted to make a booking, and that I'd heard there was a Mil discount. They took the details of the flight I wanted and then subtracted the discount. The original price I quoted in my earlier post was the internet booking price and the discount price was what the telephone booking operator quoted.
I've got this discount twice now, both for internal UK flights. I've never tried on foreign trips as the only foreign travel I've done recently have hot & sandy or cold & windy on ops.
As to your BMI Baby question - I honestly can't remember! (Old age) But there's no harm in phoning up and asking; you lose nothing if they say no and gain a great discount if they say yes!!
Oops - just noticed someone else got there before me
