Thanks! How about on domestic US flights between major cities? I really want to get the 45L Lufthansa Alu but I don’t want to have to check it a lot. Really Hard decision for me to make but I wonder if your carry on gets more scrutiny if you do not check a bag? I always get a free checked bag so maybe I should just go with the 34L .... out of curiosity do you just take the 45L on board or do you also take a personal item? How many suits do you usually pack in the 45L?
