Time savings were the reason for my using Cambridge-Manchester on Suckling Airways. I live 30 minutes from the airfield, 30 minutes check-in, 30 minutes flight and 30 minutes to my destination at Manchester, so 2 hours overall and the same back in the evening for a total of 4 hours travelling. The best I ever did in a car was 3 hrs 30 minutes one way and the worst was 7 hours one way due to roadworks on the M6. I must confess I don't remember paying £250, I thought it was in the low £100s but it was worth it for the home cooked food and wine served from full-sized bottles. Plus their time-keeping was also very good in my experience.
