I'm buying many fly tickets, but how you can ensure me that they do not retract a reservation? In Bitcoin and cryptocurrency world it can be only escrow. Do we have any escrow that can guarantee this kind of transactions?
I don't thing escrow is a good option here. I mean for security is but someone maybe buy the ticket in last minutes and wants just to receive the e-ticket in his email ,print it and go to jump on the plane. In such case escrow can only delay you the arrival of the e-tickets. The only choice is for these websites to add trustpilot a trust review for businesses website and for us to believe them first. We can try very cheap flights as a beginning of only 20-30 euro. I didn't know any website used to sell electronic flight tickets with bitcoin and I am very pleasantly surprised to see not just one but some of such websites.
