There used to be an online travel website that let you book the type of fare you wanted to travel on, and also let you combine a flexible/semi flexible with a non flexible fare.
For instance it allowed you to book a BA flight traveling B one way and M the other.
I don’t think this website exists anymore, but is there any other online booking system that lets you do this? or is the only alternative to call BA reservations?
Any of the normal sites like Expedia/Travelocity/Opodo etc will just offer me a Y fare if I ask for flexibility.
