While I am normally quite a fan of FlyBe (and the turnaround they have achieved) I am uncomfortable with this one ....
I normally have absolutely no idea how much baggage (or how many bags) I am going to have at the time I book.
I have insufficient patience to go through a negotiation and payment everytime I check in (and object to be charged extra because I couldn't estimate it at the time of booking).
I assume I will now book at least one bag, when I book the flight (to hopefully reduce the nonsense at check-in) which means my fare has gone up by UK£1 !!
I forsee check-in nightmares for all - I had to read their email three times to understand the combinations !!
