So if I am understanding, he had a reservation to BWI or IAD that was cancelled twice due to weather. Can the airlines control the weather? Your brother wanted to change his arrival city at no charge? Southwest will reschedule your flight at no difference in fare if they have to cancel due to weather, or they will refund your money. Can you name another airline that will make the same offer? Because he probably had an advanced purchase fare, making the change with less time available is going to be at a higher fare. Business just does not work that way. Moving for work is a great opportunity. It is just unfortunate that the weather did not appear to cooperate.
