What this record covers and what it does not. It gathers the 0 catalogued routes on which Spirit Airlines appears — those relevant to travellers leaving or entering Mexico — not its full network. Baggage and programme data come from our own carrier record and are checked against the airline’s site; where a field does not exist it is marked unknown rather than filled with an industry-average figure.
Local brand recognition 4/10, 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.
Baggage & family
0 kg of checked baggage are included in Spirit Airlines’s base fare: it is bought separately, and that fee is what decides whether it remains the cheap option. The infant fare sits at 0% of the adult fare per our carrier record, across 0 catalogued routes to or from Mexico.
Spirit 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:
| Item | Detail |
|---|---|
| Checked baggage (economy) | 0 kg (bought separately) |
| Carry-on | ~10 kg + personal item |
| Migrant/paisano program | Ultra-LCC pay-per-bag |
| Additional paisano baggage | — |
| Infant fare | per fare |
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 Ultra-LCC pay-per-bag programme attaches to specific fare families: buy the cheapest bucket and the benefit does not travel with you. 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: Spirit Airlines is a US carrier and DOT regulates refunds and denied boarding, not payment for lost hours. On its 0 catalogued routes departing Mexico, Mexico’s Art. 47 Bis does apply, and that is the real claim route.
Spirit 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 Spirit 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 Spirit Airlines
On the pairs Spirit Airlines operates, our catalogue lists 0 alternative airlines. With 0 kg (bought separately) of allowance and 0 routes covered, there are clear scenarios where another option returns more for the same money. On 0 of those pairs three or more operators compete.
- If you need checked baggage included: Spirit Airlines’s base fare does not carry it (0 kg (bought separately)); add bag costs before comparing.
- If you collect miles in a global alliance, Spirit Airlines belongs to none, so points won’t transfer.
Carrying a bag, Spirit Airlines stops being the cheap one. Its base fare excludes checked baggage, so the honest comparison is price plus bag fee against a full-service fare that already includes one. On short sectors that sum usually flips the search ranking, and with two pieces the flip is near certain. Travelling hand-baggage only, though, it is hard to beat.
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.
