Just passed through the final hurdle at Chicago International. On my way to Abu Dhabi. Though I had bought my ticket from American airlines, my two main flights are with Eitehad Airlines, which probably is an Emirate airline.
So, even though I got my boarding passes at DFW, when I tried to pass through the security area, they informed me that I had to go back to get new boarding passes. That took about three hours. But now, finally, I am past the security checks and all other hassles and waiting for my flight to Abu Dhabi.
The International terminal at Chicago is quite unimpressive, congested, and crowded. There are not even any good places to eat. The wait did help in one way though: I was able to smoke my fill before boarding my plan.
