Status matches are a popular way of reaching elite status quickly. Frequent travelers often hold status with one airline, offering perks and benefits when flying with that airline (and others if that airline is an alliance member). Of course, this severely limits the appeal of flying with other airlines where no benefits will be offered. Top-level benefits include complimentary upgrades, lounge access, extra baggage, and priority check-in and boarding. This creates major incentives to stick with the same airline or alliance partners when traveling.
