I traveled to Cleveland from BWI first time becuase i was going for business. I used to travel by Southwest direct flight. 4 hrs delyaed at Detroit I missed my business meeting. It took me 7 hrs to reach to Cleveland vs 2 hrs direct flight. While coming back it delayed more than an hour at JFK. Sat on Tarmac for 45 minutes just because they loaded more luggage from previous flight. Pilot informed us that plane is heavy now we need to burn fuel. First time heard about this stupidity. Power sockets were not working. Not flying again to Cleveland by Delta.
