LaQuinta Returns joins Southwest Rapid Rewards, the fourth airline partnership for the Texas-based hotel chain.

Effective immediately, travelers who stay at participating LaQuinta hotels can opt to earn .5 Rapid Rewards credit — in essence, providing a free trip on Southwest after just 32 stays.

Of course, Returns members can continue to opt for Returns points, as well, and earn 10 points per dollar spent.

LaQuinta, a mid-scale chain of more than 350 hotels nationwide, launched a completely restructured loyalty program last fall, incorporating airline, restaurant and retail partners, in addition to introducing a three-tiered elite-level program. The company spent more than a year studying and retooling the program, which for years had been limited to a 10-stays-for-a-free-night formula.
