There is this ongoing myth from the flying public that somehow the airlines are delaying flights on purpose...beats me as to WHY anyone would think this. I CAN say that the airlines do a poor job of educating the public about severe weather and it's effects between the distinations travelled. Yes, city A may have clear weather, as City B may as well...BUT, the inbetween could have had a huge storm cell develope, causing havoc.
I know many get tired of hearing about the busy northeast flying corridor, but it is true that a huge storm cell in that busy area does create many reroutes. I just wish all parties would understand that if expained in a logical and informative way, it won't scare the flying public, as many in the industry feel would happen. I try to explain what happens as the equivalence of a traffic jam caused by, say, construction or an accident. Everything slows down. When explained in such a way, the customer is more at ease.
My #1 recommendation when traveling..especially in the summer? IF POSSIBLE, take the first flight(s) out in the morning and a non-stop if available. While this is not risk free, the chances are much better to get to your final destination on time or at least that day. 😉
