Singapore to London Heathrow is a heavily-trafficked long-haul route operated by multiple carriers. Distance is roughly 10,860 km (6,750 miles), with westbound flight time around 13 hours 30 minutes and eastbound around 12 hours 45 minutes.
Who flies it
Singapore Airlines, British Airways, and Qantas (as part of its kangaroo route to Sydney) all operate the route. Singapore Airlines typically runs multiple daily non-stops with the A380 and A350-900ULR. BA uses the 777 and A380. Qantas uses the 787 on the SIN portion of its onward Australian service.
Practical reality
Westbound is a daytime flight in both directions of the route's daily cycle — Singapore Airlines typically operates a morning departure (arriving London afternoon) and a late evening departure (arriving London early morning). Eastbound is mostly evening departures landing Singapore the next afternoon.
