A good idea at the time, but ...
Well, we took a chance and booked to go to Japan from Cambridge via CDG in March. Good, competitive price.
We made a through booking with Opodo - not separate bookings.
First thing that happened was that the return flight CDG-CBG was put back one day = one unwanted overnight in Paris with no offer of accommodation.
Now the outbound CBG-CDG has been brought forward one day = another unwanted overnight in Paris (of course the flights to Japan haven't changed!) and again no offer of accommodation.
AND of course both CBG-CDG and CDG-CBG flights have now become dog-legs, so outward is now CBG-AMS-CDG and return is now CDG-AMS-CBG.
If I had wanted to do a tour of Europe, then I would have said so at the outset!
I don't think that Darwin (now Etihad Regional) have really advertised the CBG flights and they seem to have let them wither on the vine. Well, lesson learned!
