From O'Hare (ORD) there are four weekly flights on Monday, Tuesday, Thursday, and Saturday; from Midway (MDW) there are three weekly flights on Tuesday, Thursday, and Saturday.

If you are a U.S. citizen, you do not need a visa to enter Mexico for tourism or business for stays up to 180 days, but you must obtain a Forma Migratoria Múltiple (FMM) upon arrival. If you are a Mexican citizen, you generally need a visa to enter the United States unless you hold a valid U.S. visa or are a member of the Visa Waiver Program (which Mexico is not part of).

Taxis are available outside arrivals from 4:30 am to 11:00 pm through authorized operators, offering a direct ride. Ride-share services like Uber also operate at the airport, and car rentals are available from agencies including Alamo, Avis, and Hertz.

It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.", "toolsUsed": [ "seasonal_prices" ] }, "q5": { "question": "How far in advance should I book tickets from Chicago to León?", "answer": "For Chicago to León, the best fares appear when booking 16 to 19 weeks ahead, with an average price around $507. Booking around 125 days out can yield the lowest fare, near $497, while waiting until the last week pushes prices above $600. During summer and holidays, demand typically shifts the ideal window earlier, so aiming for 4–5 months ahead is safer.", "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.", "toolsUsed": [ "booking_timing" ] }, "q6": { "question": "Are overnight (red‑eye) flights available from Chicago to León?", "answer": "No nonstop red‑eye flights operate from Chicago to León, but connecting itineraries whose long leg is an overnight flight are available.

It does not have scheduled commercial airline service, so there are no regular public transit options like trains or shuttle buses directly from downtown Chicago. The most practical ways to reach the airport are by taxi, ride‑share, or driving and parking in the on‑site lot; driving is fastest and most popular, typically taking 45–60 minutes via I‑290 and I‑88.
