I was so surprised to find that i did not like this bag at all and that ot was very cheaply made.  I cannot believe all the amazing reviews.  1.  The bag does bot fit inder the seat.  2. Awkard to pull and not balanced and often falls over.  3.  Doesnt carry much and hard to access the.main compartment due to attached plastic.  One of my plastics was bot sewn on properly.  Sode pockets and all pockets are really tight and don't fit much.  Sorry i spent the money for this.
