I don't have bills and shit but I can't understand not being able to save.
Say you work full-time and get paid weekly.
All you need to do is save $100 a week.
Unless you're struggling to survive (in which case travel should be the least of your worries) $100 should be very easy to save.
Now if you put aside $100 a week, in one year you will have $5,200.
That is enough for a plane ticket anywhere in the world plus hotel and food unless you're a boomer who wants the most expensive of everything.
People who say they can't afford travel can in fact, afford it. They just can't be bothered saving for it.
Even doing $50 a week lands you $2,600 which is enough for a nice holiday.
