A route to Bangkok may offer a choice between a close connection and a pause in Dubai or Doha. The useful question is not whether every traveller should add a stop, but whether the available time could be used better outside the airport than inside it.
A night or two can change the rhythm of a longer trip. It can make an early arrival more manageable, create room for a city that would otherwise remain only a view from the aircraft window, or simply give travellers time to arrive properly before continuing.
