Pros: Generally, I like Insel.
Cons: I fly with Insel a LOT and recently I have had to argue with Insel employees about whether I am allowed to board with a standard sized piece of carry on luggage. I have used this same luggage as my carry on for pretty much ALL flights that I have ever had with ALL airline companies EVER. It ia the max allowable size. It DOES fit in the compartment above the seat. It is standard carry on size and I don't want to have to buy another just because I have to argue with an Insel employee every time I fly. It makes me feel unwelcome as a customer and uncomfortable. Please be more gracious to good, respectful customers who try to adhere to rules (I always try to be really good about checking the weight of my luggage and try to be polite and respectful to all employees.)
