Took a trip last week via Chicago O'Hare Airport, and what did I realize? Holy cow! If you are into bags like many of us who are stricken with this disease, a large airport is the place to be. I found myself not even too interested (well not too) in the lovely ladies. There were interesting bags all over the place. Some observations. Sling Bags: Very few sling bags at the airport. I don't know if they haven't caught on for carry-on, or people have found that they just don't work well (too heavy) for all the carry-on junk we might take, i.e.. laptops, tablets, etc. etc. Backpacks: Still very popular, but tend to be overloaded (to avoid checked bag charges) and too chubby to fit in the overhead bins. Tactical backpacks tend to be somewhat regional to military facilities, i.e.. Little Rock, AR. happened to have a large number of uniformed and non-uniformed carrying tactical backpacks (perhaps making connections for training or deployment?). Many backpacks appear to be trendy brands, Swiss Army, North Face, etc. Rollerboards: Still the most popular method of airport transport. Sometimes difficult to believe the size of these for carry-on. I didn't know that some of these aircraft have expandable overhead bins! So excited about airport bag watching that I can't wait for my next trip in September. What do you think? Is it a terminal case of bagitius? Is there a cure? BTW, my bag of choice was my new Hazard 4 Evac Take Down. Due to it's black color and slim design it worked great. If you don't mind the narrow folding of your clothes I managed to fit enough for a five day trip. Added bonus, since it is so thin it easily fit in the over-head bin of a regional jet.
