I once took a Boston -> London flight that arrived significantly early thanks to the arctic jet stream. But that meant we arrived before the landing curfew ended at 6am so the aircraft was put in a holding pattern above central London for 30 mins or so, and I flew more or less over my home in East London a few times (I could see it out the window as we flew overhead). We landed a few minutes after 6am, and by the time I got through immigration and customs and rode home during the morning rush hour on the tube it would have been 8 or 8:30am. Super frustrating that the last mile took 3 hours to complete!
