I normally just take a laptop bag and it serves as an extra place to store my jacket and small things. I kind of get it for local flights ,but definitely not international flights because you need the baggage. I am amazed that there are ticket options for those with no suit case or carry on baggage for international flights. Most of the flights we do now are upper economy so you are allowed extra bags depending on the airline which may also include 2 suitcases per person.
