Wayne is right - and booking them yourself is often cheaper. I have used BMI from Edinburgh to Manchester several times. I just ran a quote this weekend for our dates in case there are better deals flying from MAN/LGW and they came back at around £150 return for myself and DD, including taxes. You still get your 20 kg luggage allowance (only 3 kg less than the VA flight) and if you are really worried about luggage allowance you can look into prepaying an extra bag - still leaving you a lot better off than paying full fare and/or booking connections with a TA. BTW I also ran quotes from GLA for the sake of comparing timing so either is an option.
