LHR to Bejing, LHR to Bangkok, LHR to Laos, and Cambodia back to LHR. And LHR to Havana, and to Panama and Mexico, have IME always involved a refuelling stop.

The same with flights south to the African continent; being with European carriers, always stop in their home country, where you will, more often or not, change flights. And the same with some Asian countries: Burma, Bhutan (via India) and Nepal.

The only non-stop flights I have made have been to some Middle Eastern countries, and some North African countries (Egypt, Tunisia, Morocco, Mauritania etc.)
