Why is it cheaper for me to fly via another country rather than a direct fligtht from the UK?
When travelling east from the UK, on mainly long haul flights, i always find it is cheaper to fly an airline located part way to my destinations. Why is this?
An example being,
i normally fly from the UK-DEL, and british airways is always THE most expensive. I find it cheaper for me to fly an airline based on mainland europe (e.g. air france e.t.c) to asia, with a connecting flight through their hubs.
Do i just pay for convenience of a direct flight and the almost (AI) manopoly they have on this direct flight, or is there something that i am missing. I am 100% sure it would be more expensive for an airline to fly me to say CDG and then DEL, rather than a direct flight, yet the mainland european airlines always come cheaper.
The same is for travelling to the US- i dont have experience with this, but from looking at cheap ticket websites, i can normally fly via mainland europe to the US for at least the same price as say a direct fligtht from the UK to the U, or maybe even cheaper.
Im just curious, im not complaining though.
