Reach in the Mexican market. Its catalogued routes span 641 km (MTY-HOU) to 1,962 km (PVR-LAX), measured great-circle between airports. That range matters because distance decides aircraft type, the usual allowance and — on sectors touching Europe — the compensation band that applies if the flight is delayed.

Local brand recognition 6/10, and what it means. This is our own awareness score in the Mexican market — not a measure of punctuality, safety or service — used to compare carriers against each other inside this site. A highly recognised brand tends to sell the same seat dearer because it captures direct search; a less known one competes on price in the comparator. Read it as a market signal, not a quality one.

Southwest Airlines routes from/to Mexico

Where it actually competes. On 5 of its routes three or more airlines share the pair, and there Southwest Airlines’s pricing is disciplined by its neighbours: MEX-HOU, MTY-IAH, MTY-HOU, PVR-LAX, SJD-LAX. In those corridors compare with the bag already included, because the base-fare gap between operators is usually smaller than the baggage fee.

Baggage & family

Southwest Airlines includes 23 kg of checked baggage in its base economy fare, with the infant fare at 0% of the adult one. Its Bags Fly Free (2 maletas gratis 23kg cada una) programme adds benefits for recurring travellers. It operates 5 catalogued routes to or from Mexico.

Southwest Airlines applies the following baggage policy. Paisano travellers visiting family should check the airline’s program before buying, since extra bags change the total ticket cost:

The allowance belongs to the fare, not to the passenger. The kilos listed are those of the published base fare. ‘Basic’, ‘light’ and ‘zero’ families on several carriers exclude the checked bag, seat selection and sometimes date changes, even though the flight and the aircraft are identical. The carrier’s Bags Fly Free (2 maletas gratis 23kg cada una) programme attaches to specific fare families: buy the cheapest bucket and the benefit does not travel with you. Our data records 23 kg of additional allowance for recurring travellers. Always compare with the bag already added: on short sectors the ranking of operators usually flips once it is in.

Passenger rights

0 pesos of federal delay compensation: Southwest Airlines is a US carrier and DOT regulates refunds and denied boarding, not payment for lost hours. On its 5 catalogued routes departing Mexico, Mexico’s Art. 47 Bis does apply, and that is the real claim route.

Southwest Airlines is a US carrier, regulated by the US DOT. Unlike Europe, the US does not mandate fixed cash compensation for delays: the DOT requires a refund when the airline cancels or significantly changes a flight, and care (meals, hotel) for controllable cancellations under each airline’s published commitments. Mandatory cash compensation applies only to involuntary denied boarding (bumping) under 14 CFR Part 250. AirHelp does not automate DOT claims; for a Southwest Airlines flight, keep your receipts and claim directly with the airline and, if needed, the DOT.

The operating carrier decides, not the seller. The compensation regime follows the airline that actually operates the flight, not the one printed on your ticket. A codeshare sold under a Mexican carrier’s code but operated by a European one is claimed under the operator’s regime, and vice versa. The ‘operated by’ line on the boarding pass is the field that fixes who you claim from and before which authority.

What US DOT does not cover. The United States has no federal delay compensation: the Department of Transportation regulates refunds — your money back when the airline cancels or significantly changes the flight and you decline the alternative — but it does not require a payout for the hours you lost, the way EU261 does. The single federal exception is involuntary denied boarding from oversales, priced under 14 CFR Part 250; that is a different mechanism from delay and is not triggered by a late departure.

What does apply on departure from Mexico. Mexico’s Ley de Aviación Civil (Art. 47 Bis), enforced by AFAC and PROFECO, covers flights taking off from Mexican territory regardless of the airline’s nationality: a delay over 4 hours attributable to the carrier entitles you to at least 25% of the ticket price, and from the first hour the airline owes assistance that escalates with duration. Keep the boarding pass and the purchase receipt — a claim stands on those two documents.

When NOT to choose Southwest Airlines

On the pairs Southwest Airlines operates, our catalogue lists 4 alternative airlines (American Airlines, Aeromexico, United Airlines, Volaris). With 23 kg of allowance and 5 routes covered, there are clear scenarios where another option returns more for the same money. On 5 of those pairs three or more operators compete.

• If you need checked baggage included: Southwest Airlines’s base fare does not carry it (23 kg); add bag costs before comparing.
• If you collect miles in a global alliance, Southwest Airlines belongs to none, so points won’t transfer.

Travelling light, you pay for something you do not use. Those 23 included kg are inside the price whether or not you check a bag. If the trip is two days and fits in the cabin, a bag-free low-cost fare on the same pair works out better. A generous allowance pays off on the family trip and the loaded return, not on the weekend break.

When the date outranks the price. If the trip hangs on a consular appointment, a ship joining date or a family commitment with no slack, look at the pair’s frequency before the fare. In a corridor with few weekly departures, the airline running the most of its own services that day is worth the price difference, because it is the one that can rebook you without depending on third-party agreements.
