The direct route between Scotland’s third city and Europe’s busiest airport heads almost due south to Newcastle, then shadows the A1 trunk road to London. At 402 miles, a pilot flying an Airbus A320 by the straightest course could complete the journey in an hour.
But BA allows an extra 40 minutes in its published schedule. Partly the airline pads the schedule to allow for being ordered to "fly a holding pattern” before waiting to land at Heathrow, and partly because the journey actually flown typically zig-zags, adding 100 miles to the optimum path.
