Earn 75,000 bonus miles after spending $5,000 on purchases within the first 3 months of account opening.
Annual fee: $0 introductory annual fee for the first year, then $99.
Sebby's take: Get the perks of airline status, without being a frequent flyer. My favorite is free first checked bag (great for skiiers!). The annual fee is offset by 2 United Club one-time passes per year. Plus, add employee cards at no additional cost.
