In the past when I traveled to teach seminars (instead of the far more enjoyable online teaching I now do from beautiful Ventura, CA) as soon as I got on an airplane, I would head to the magazine collection and grab the Harvard Business Review. It is an excellent publication with well-written articles that often had useful application to church ministry. It is also a VERY expensive magazine and when my travel days were over, so was my enjoyment of it.
I was delighted to learn from a link sent to me by a friend that I didn't have to totally do without the advice from this useful source. A friend sent me this link to a very helpful article (lots of applications on the spiritual damage complaining can do):

Access to more content from the Harvard Business Review
When you go to the link--don't be concerned when they ask you to register. When you do, you get free access to the HBR blog, which is filled with quality materials and access to 3 magazine articles a month. Of course you will be prompted to subscribe, but you don't have to and there is a wealth of useful materials here.
