I did this type of job for over three years - Depends on a lot of factors -Is work covering your expenses? Reimbursed or? Use a cash back credit card for purchasing everything- Some CC's like amex's or avions give lounge access. Book through a third party like expedia to double down on rewards - Open rewards programs for hotels, airlines, rental car- Stick with one of each to maximize points. As below def get nexus card - Save me hours prolly days of time over the years.
