"Maybe you could share a few tips?"
Tip #1: Fly for a living. Aside from my time in JA, I'm on an airplane at least once a month for work.
Tip #2: GET the credit card - charge everything on it and pay it all off every month. Again, this works for my business really well. The 1 mile pre $1 dollar of purchase = 60,000 miles in one year sometimes.
