Flights León / Silao to Dallas (BJX-DFW): airlines, frequency

Flights León / Silao → Dallas: airlines, fares, timing

The BJX–DFW route appears in our catalogue with 10 weekly departures (~1.4 per day) across 2 airlines, 2.5 h of block time and 1,395 km great-circle between León / Silao and Dallas. Demand score: 7/10, classified as the Mexico-US paisano corridor.

Bajío (León) to Dallas links the Bajío industrial region with north Texas, with around 10 flights a week. The Guanajuato region has strong family ties to the United States, and the route carries families visiting relatives alongside business travellers in the manufacturing sector. Block time is about two and a half hours.

At ~1.4 departures a day there is daily service but little cushion: if the flight cancels, the same airline’s next option is usually the following day. Leave slack on any onward connection and avoid buying the last departure of the day when something is booked after it.

How to read these figures. Weekly departures are an aggregate estimate from the published schedules of every catalogued carrier on the pair, one-way; the flight time is block time — gate to gate, taxi included — not airborne time. Neither is a schedule guarantee: carriers cut frequencies in low season without notice.

Airlines operating this route

2 airlines operate BJX–DFW: Aeromexico, Volaris. 1 are full-service and 1 low-cost; included checked allowance ranges from 0 to 25 kg depending on the operator. Between them they run 10 weekly departures over 2.5 h of block time; alliances present: SkyTeam.

Two carriers fly BJX-DFW: Aeroméxico, full-service with baggage included, and Volaris, on a low-cost model. Both fly direct, so the decision is between a full ticket and a bare fare to which baggage is added, depending on schedule and price.

The honest comparison already has the bag in it. Between the most generous operator (25 kg) and the leanest (0 kg) there are 25 kg of difference in the base fare. Volaris includes no checked bag in the base fare, so its list price is not comparable with the rest until you add the fee. On a 2.5 h sector onboard comfort matters little; total cost is decided by baggage and, if you travel with family, by seating you together.

MXN fares — what to expect

There is no live cached fare for BJX-DFW, but 3 historical readings exist between 2026-W25 and 2026-W29: the observed floor in that window was $3,433 MXN and the ceiling $7,294 MXN. Only 34 of 109 corridors returned a price on the last pass.

BJX-DFW fares move with the family calendar — December, Holy Week and the summer are the peaks. For those dates, booking two to three months ahead is sensible. Off-season, four to six weeks usually secures a reasonable fare in MXN.

Buying window: a general market rule of thumb. At demand 7/10 and 10 weekly departures the usual reference is 4 to 8 weeks ahead on ordinary dates and 8 to 12 weeks for December, Holy Week and summer. That is a general Mexican-market rule of thumb, not a measurement of BJX-DFW: our series records observed prices, not the lead time at which each ticket was bought. What the data does support is that the lower the frequency, the sooner cheap inventory runs out.

Two currencies, two budgets. The fare is compared in pesos because that is what leaves your account, but spending at destination runs in USD. A fare quoted in foreign currency and charged in pesos by your bank adds the conversion spread, and choosing to pay in pesos at a foreign terminal (dynamic currency conversion) is almost always worse than letting the bank convert. Budget the flight in MXN and the stay in USD separately.

How the BJX-DFW fare has moved

Across 3 weekly readings between 2026-W25 and 2026-W29 of 2026, the detected minimum for BJX-DFW moved between $3,433 MXN and $7,294 MXN, a 112% range. The cheapest reading fell in week 2026-W29. The latest reading sits 53% below the one before it.

How to use it when buying. If today’s quote sits near $3,433 MXN you are at the low end of what was observed in this window and waiting rarely pays. If it is above $7,294 MXN, or your dates fall in December, Holy Week or summer, the figure you see is probably seasonal rather than structural. In no case extrapolate the series forward: six readings do not predict the seventh.

What a 112% range means. Dispersion like that between readings taken in different weeks says the price of BJX-DFW depends far more on when you look and which dates you search than on the airline. It is not a trend: these are point samples of the available floor, and a low floor usually corresponds to awkward dates — pre-dawn departures, midweek, off-season — rather than to a general market drop.

Passenger rights on the BJX–DFW route

25% of the ticket price is the minimum Art. 47 Bis of the Ley de Aviación Civil requires on the BJX → DFW leg, which departs Mexico, for a delay over 4 h attributable to the airline. On the return from the United States there is no federal delay compensation.

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.

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.

Documents to sort out before buying

Verified 2026-05-18: with a Mexican passport, Estados Unidos requires Visa B1/B2 obligatoria, at a cost of $185 USD no reembolsable and a maximum stay of Decidido en POE; típicamente 6 meses. Confirm the current amount before paying. Buying the ticket before the document exists is the expensive mistake on this route.

Check the current amount before paying. The consular fee and stay limit above are the ones in our immigration file, last verified on 2026-05-18. Consulates revise those amounts without notice and publish no change calendar, so confirm the current figure at the official source on the day you pay. A receipt issued at the old rate is neither refunded nor credited — it is simply paid again.

The right order: document first, ticket second. A cheap fare does not survive a pending immigration formality. The airline will not refund a non-refundable ticket because your visa was denied or delayed, and the change fee usually exceeds the saving you were chasing. Consular appointment waits run 30–180 days depending on the post, and buying the ticket first does not speed them up. Buy once the document is issued, or buy a changeable fare and accept that the premium is the price of the risk.
