The pre-owned jet market has split in two. Late-model airframes with modern avionics sell quickly and hold their asks. Everything else — and it is now the large majority of listed inventory — sits, ages, and gets marked down in instalments. If you're hunting reductions in aviation, you are almost by definition shopping in the second pile, and the second pile has rules.
An older airframe isn't cheaper because the market is inefficient. It's cheaper because the next owner inherits the calendar: engine programmes coming due, avionics mandates, interiors from another decade, and a resale market that will apply the same discount to them that they're currently enjoying. The reduction is compensation for those costs. The buying question is whether it over- or under-compensates — and on multi-cut listings that have sat past a year, it frequently over-compensates, because the seller is pricing their frustration as well as the aircraft.
Two identical airframes with identical hours can be hundreds of thousands of dollars apart in real value depending on whether engines and APU are enrolled on maintenance programmes and whether the paperwork is complete and continuous. A deeply cut aircraft with no programme coverage is often the expensive one. Before the pre-buy inspection — which you will do, at a shop you chose, not the seller's — the logbook review is the cheapest diligence you'll ever buy.
Aviation sellers are disproportionately corporate: flight departments consolidating, charter operators rotating fleet, lessors clearing returns. These sellers mark to internal policy, not emotion — which is why aviation produces the cleanest capitulation signals of any asset class we track. A fourth markdown from a corporate seller at fiscal year-end is about as close to a printed reservation price as this market gets.
Whatever you pay, the aircraft costs what it costs to run — crew, hangarage, insurance, programmes, fuel — and on an older large-cabin that floor can exceed the purchase price within a few years. The markdown buys the airframe. It does not buy down the floor. Model the five-year total before celebrating the entry price.
