want to book a flight. And as usual: Flight from A to B is good, but return flight is bad. Flight from A to C is bad, but return flight is good. And no way to combine the good flights with keeping at least roughly the same price. Not to forget that I actually want to go to D, but flying there is considerably more expensive than to either B or C (would also go via E with quite some layover) and taking the train afterwards (80€ flight + X train vs 200€ flight).
