vctenderness, you saw EI-LNB (with Thor Heyerdahl on its tail) arriving from Stocholm Arlanda with flight number DY2853. Gatwick gets this summer a twice daily 787 crew training flights on weekday. The last day of this service will be on Thursday 24 July. Gatwick saw similar flights last year flown with their at that time only 787 (EI-LNA), but all flights then originate at Oslo Gardermoen.
One hour behind EI-LNB today EI-LNG (Edvard Munch on its tail) arrived from Los Angeles. November Bravo was 1 hour 45 minutes late on arrival after an almost 2 hour 30 minutes late departure from Gatwick yesterday due to a technical issue. I fear tomorrow's arrival from JFK will as late as today's LAX arrival since the departure today to JFK from LGW was around 40 minutes late. JFK turn arounds tend to lose in average 1 hour, with half of it due to poor ground handling and the other half due to slow taxiing and waiting in line for taking off. The flight times to and from has got the usual JFK padding, but this summer has been worse than ever.
