Hmm - well - I am trying to calculate the correct travel time to Luton Airport next Sunday morning. National Rail Enquiries indicate that pre-0900hrs. departures from St. Pancras to Luton Parkway take 45 minutes. So - add on all that Underground time from EC2 to St. Pancras (say 25 minutes ?) and we should arrive at Luton Airport Parkway after 1hr 10 minutes assuming there are no delays. Then - up and down the stairs at Parkway - then wait for the shuttle. Say a 15 minute trek in all??? Say 10 minutes to Luton Airport and a 5 minute walk to check-in / arrivals. 1Hr. 40 mins in all. Hmmmm.
