It makes good resume material. You have proved that you can conform, follow rules, are disciplined, have leadership ability, a team player, able to handle stressful situations, and host of other valuable skills that airlines look for. So of course having that experience is ALWAYS to your advantage.

Whatever airline you want to go to work for is going to call you for interview based on your flight experience.

When they interview you, the choice to hire you is going to be based on how you handled their interview, as well as how good of a job you did selling yourself on how well you will fit into their company. As well as whether or not they can handle flying a 4 day trip with you.
