Hey there, very similar too. I went to college then onto Uni but left Uni after i applied and was succsesful with my first airline job. Up to then i had a limited amount of travel. i dont think i regret joining before i had the chance to do more traveling. With the industry always changing i didn't want to risk loosing a shot at my dream job. Since then i have travelled more than ever (and im SH) Spain America and now im of to Oz for a month!!
Its a hard choice, but whats more important to you? If your confident that you can be succsessful in another interview then go traveling. Im sure the pension contributions could hold off one more year lol
good luck
