Ride-share services like Lyft and Uber pick up on Level 5 of the Domestic Garage, while taxis are available at the center islands outside Arrivals. Rental cars are centralized at the Rental Car Center, accessible by AirTrain Blue Line, and many hotels offer complimentary shuttles. An autonomous Waymo ride-hailing option is also available for select passengers at the Rental Car Center.

The most expensive months are April, June, and May, averaging $493–$527.", "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). 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 Detroit to San Francisco?", "answer": "For the Detroit to San Francisco route, the best fares are typically found when booking 3 to 6 weeks ahead, with an average price around $311. The absolute cheapest single ticket appears about 35 days out at $297, while prices climb sharply for last-minute bookings and can spike above $600 if booked 5 months early.", "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 Detroit to San Francisco?", "answer": "Yes, Delta operates a nonstop red-eye from Detroit to San Francisco, departing at 9:24 PM on Saturdays.
