After 83 minutes departure delay at Oslo Airport this morning due to malfunctioned airplane, the pilots made a great effort to catch up and was scheduled to arrive London Heathrow only 49 minutes after estimated arrival time.
However, that was without unexpected delay at Heathrow.
Circling 4 times north east of London before getting admitted to line up for landing ate up all the saved time plus a little more. Traveling to London with SAS can be a challenge.
When grounded at Heathrow as seen on this image from Flightradar24.com , the pace to get the luggage and the National Express bus bound for South Wales became another stressing challenge.
