Fares bottom out in October around $333 and peak in August near $628, 89% dearer, across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 9.5 hours outbound, on a 23-night trip — ticketed under TAP Air Portugal, which on a connecting fare need not operate every leg. At $376 for 7,091 km each way, that works out to about $27 per 1,000 km flown. That is well under the $44 per 1,000 km that long-haul fares on this board typically run. Across the 12 departure cities we track at a similar distance from Madrid, this fare ranks 5th — 24% above the $303 from New York. It is also the cheapest of the 28 routes of similar length we watch out of Miami. The best time to be in Madrid: Apr–Jun · Sep–Oct.

We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 6 months of cached fares, Oct comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
The current cheapest fares involve a connection, ticketed under TAP Air Portugal. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
No — these are cached fares found on real searches (this one on 17 October). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
