I am doing an eclipse run. I purchased two one-way fully refundable tickets rather than a roundtrip and I just want to make sure there are no flaws in my logic. If both fully refundable, I really don't see any obvious benefits to booking a roundtrip. If things go south (weather forecast changes (I am not going if its going to be cloudy), irrops, etc.) I can cancel both tickets and get my money back. Once everything is a go, and I am fully committed, am I able to change my refundable ticket into a nonrefundable fare if the nonrefundable fare on the day of travel is lower (it probably wont be, but you never know)? This was the primary reason I booked one-ways. Anything I am missing?
