i wanna book but if they cancel doesnt pay the hassle
Ok then there is no point in paying attention to these type of deals. Some they keep some they cancel. You never know till something happens. Did you book it originally, did you book the El Al glitch? Did you book the delta glitch? The thing about these happenings is to book, if it gets cancelled it gets cancelled. But if it gets honored you are good and nothing will happen.
You just have to play and hope for the best.
