Hello! I've been reading the forums for quite some time but never registered/posted, but here I am with a question for you (the experts)! I'm in my early 20's and just started a full-time career with a consulting firm doing Tech Strategy consulting. Almost all of my projects will require weekly or bi-weekly travel so I come to you for help. All my travel costs are reimbursable so I don't necessarily ALWAYS have to book the absolute cheapest option. What airline should I aim to fly the most? What hotel chain should I stay at the most? Would it be beneficial to stay at one chain Monday-Wednesday and another Thursday-Friday? Any particular credit card(s) I should use? Flying Info: Home City: New York City Frequency: Round trip per week (2 flights) Rewards Desired: 1. Free upgrades(from economy to economy comfort, exit row, business class, etc), 2. Airline Lounge access, 3. Redeem free flights (very flexible on dates). Hotel Info: Travel Destinations: Mix of big/small domestic cities. First assignment is in Mexico City (rare case, most will be domestic at a mix of big/small cities) Nights per week at hotel: 3-4 Type of Hotel: $100-200/night (SPG, Hyatt, Hilton, Marriott, etc) Rewards Desired: 1. Free wifi, 2. Redeem free nights (again, flexible on dates) Thanks for the help!
