The cheapest itinerary we are tracking makes one stop and takes about 11 hours outbound, on a 6-night trip — ticketed under Icelandair, which on a connecting fare need not operate every leg. At $761 for 7,082 km each way, that works out to about $54 per 1,000 km flown. That is above the $44 per 1,000 km typical of long-haul fares here. Across the 12 departure cities we track at a similar distance from Alicante, this fare ranks 9th — 2.1× the $368 we hold from Abu Dhabi. For context, the middle fare among the 33 routes of similar length we watch out of Chicago is $729. We have 2 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage. Fare history here is still too short to name a cheap season. The best time to be in Alicante: May–Jun · Sep–Oct.

Route facts
Good to know
We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers the levers we can measure.
The current cheapest fares involve a connection, ticketed under Icelandair. 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.
