Johnny,
Let us say we compare Plymouth to Coventry, after they both had the sh!t bombed out of them during WWII, CVT has BHX 10 minutes up the road or railway line and/or be delivered to the door of LTN airport by National Express in circa 1.33 hours in t'other direction.
So, precisely how long, and by what mode(s) of transport, does it take to travel from Plymouth to EXT airport, how much does it cost and where the bl00dy hell can one fly to at the passengers desired time from EXT?
