Southwest Airlines isn't the no-frills-no-fees carrier it used to be. Assigned seating, checked bag charges and a new four-tier fare structure have all arrived, so its Rapid Rewards loyalty program works a little differently than many frequent flyers remember. The good news: points are still easy to earn and use, there are no blackout dates, and the program's standout perk — the Companion Pass — remains one of the best deals in airline loyalty for anyone who usually travels with a partner.

Point values now float rather than tracking the cash fare. In recent testing, redemptions have returned anywhere from about 1.1 to 1.7 cents per point depending on demand and date, with a typical value around 1.25 cents — so 10,000 points is roughly $125 off a flight. Points never expire unless you close your account.

Earning is flexible. Paid flights earn 2 points per dollar on Basic fares, rising to 6 on Choice, 10 on Choice Preferred and 14 on Choice Extra. Chase's five Southwest credit cards offer welcome bonuses from 50,000 to 80,000 points, and you can move Chase Ultimate Rewards or Bilt points across at 1:1. You can also buy points (from 2,000 up to 60,000 a day, usually at 3 cents each — only worth it during sales). Notably, flights booked through Icelandair, Southwest's first international airline partner, now earn points that count toward status, though other interline partners like EVA Air don't yet participate.

Elite status comes in two tiers. A-List needs 20 qualifying one-way flights or 35,000 tier qualifying points in a calendar year, unlocking free checked bags, Group 1 boarding, better seat selection, a 25% flight-points bonus and free same-day standby even on Basic fares. A-List Preferred doubles the requirements (40 flights or 70,000 points) and adds extra-legroom seats at booking, two free bags, boarding ahead of Group 1, a 100% points bonus and free premium drinks. Credit card spending can contribute tier qualifying points — for example, 2,500 points per $5,000 spent on the Priority card — but purchased points and most bonuses don't count.

Redeeming works like a cash booking: search on Southwest's site and tick the Points option. Taxes and fees start at $5.60 one-way, and award tickets can be cancelled free. One catch: Basic fares are restrictive — cancellation returns a flight credit (expiring in six months) rather than a refund, and changes require upgrading the fare first. Higher tiers add seat selection, flexibility, refundability and, on Choice Extra, two free checked bags and a complimentary drink.

Why should a traveller care? If you fly Southwest even occasionally, the math is compelling: cardholder perks like a first free checked bag for you and up to eight companions on the same reservation can offset the airline's new bag fees, and savvy Basic-fare bookings paired with the Companion Pass can make couples' travel remarkably cheap. Just read the fare rules before you book — the fine print now matters more than it used to.
