Jet fuel has more than doubled since late February. Australian domestic fares haven't moved yet — at least not in the data. Here's what 34 years of BITRE history tells us about what comes next.
BITRE Air Fares Index 1992–Mar 2026·Updated 14 April 2026· Updated with each BITRE release
Every major fuel shock in Australian aviation history has pushed through to ticket prices, typically with a 2–4 month lag. The 2008 oil crisis, the post-COVID demand surge, the 2011 floods and Qantas grounding — they all show up in this data. The question isn't whether fares will rise. It's by how much, and how fast.
The March 2026 BITRE index — the last data point before crisis pricing took hold — shows best-discount fares at 71.0, up 9.8% year-on-year but still 20% below their pre-COVID peak. The June 2026 release will be the first to capture the actual impact.
Data note
What the index doesn't show yet: The Iran conflict began 28 February. Qantas and Virgin began raising fares in March. The March 2026 BITRE index captures fares in the survey window before those increases fully registered. The June 2026 release is the one to watch.

Lower index = cheaper fares. CPI-adjusted strips out inflation — use it to compare real purchasing power across decades. Restricted economy series begins 2001. The shaded region at the right marks the start of the 2026 fuel crisis; BITRE data has not yet captured this window.
The 2008 parallel: what happened last time fuel doubled
The closest historical parallel is the 2007–08 oil shock, when crude hit US$147/barrel in July 2008. Australian domestic best-discount fares fell 14.3% in real terms over that period as airlines competed aggressively for contracting demand. The shock was absorbed, then reversed.
The 2026 situation differs in one critical way: there's less competition to absorb it. Rex has retrenched to regional routes, Bonza collapsed in 2024, and the market is a three-carrier duopoly on most trunk routes. Less competition means less pressure to discount through a fuel shock — fares may rise faster and recover more slowly than 2008 suggests.

How we got here
28 Feb 2026
US-Israel strikes on Iran. Strait of Hormuz effectively closes. Jet fuel markets reprice immediately — contracts up 20% within days.
Early Mar
China halts fuel exports. Beijing orders refiners to stop all refined fuel shipments. Australia sourced ~32% of jet fuel from China.
Mid Mar
Reserves confirmed at 29–32 days. Six tankers cancelled or deferred. Government releases 20% of diesel reserves. BITRE survey window closes.
Late Mar
Jet fuel hits $195/bbl globally (IATA) — a 96% increase in a single month. Qantas and Virgin confirm airfare increases.
Apr 2026
Jetstar trims trans-Tasman by 12%. Air New Zealand cuts 1,100 flights. Fuel surcharges on some routes up 140% since February.
7 Apr 2026
Conditional US-Iran ceasefire. Hormuz traffic at ~10% of pre-war levels. Analysts expect months before supply chains normalise.

When data confirms
BITRE June and September 2026 releases
Business class fares in real terms are at their lowest levels in 30 years — the March 2026 index sits at 52.6, against a 2016 peak of 94.8. That reflects a structural shift in corporate travel policy, not a crisis effect. The fare types most exposed to fuel cost pass-through are best-discount and restricted economy, where airlines have the most pricing flexibility.
One pattern history consistently shows: fuel surcharges, once introduced, rarely come back down even when fuel prices do. Airlines introduced them as temporary measures and kept them permanently. The current crisis may prove the same.
What to watch
Energy Minister Bowen flagged that Chinese jet fuel supply is only locked in until late April or early May. Whether replacement supply from India or South Korea fills that gap will determine if Australian airlines face domestic capacity cuts next.
Frequently asked questions
Based on 34 years of BITRE data, every major fuel shock in Australian aviation has pushed through to ticket prices, typically with a 2–4 month lag. With jet fuel prices more than doubling since February 2026, fare increases are expected to appear in the June and September 2026 BITRE releases. The only real variable is magnitude — the 2026 market has less competition than 2008, which may accelerate the pass-through.
Historically, Australian domestic airfares reflect fuel cost increases with a 2–4 month delay. This is partly due to advance bookings, airline hedging contracts, and the BITRE survey cycle (which adds a further ~60 days of reporting lag). The March 2026 fare index was surveyed before crisis pricing fully registered — the June 2026 BITRE release is the first data point that will show the real impact.
During the 2007–08 oil crisis, when crude hit US$147/barrel, Australian best-discount domestic fares fell 14.3% in real CPI-adjusted terms — from an index of 91.8 in 2007 to 78.6 in 2008. Airlines competed aggressively for contracting demand, which ultimately dampened the fare spike. The 2026 market has fewer competitors (Rex retrenched, Bonza collapsed), which may produce a different and more sustained outcome.
Best-discount and restricted economy fares are most exposed to fuel cost pass-through, as airlines have the most pricing flexibility in these categories. Business class fares are already at 30-year real lows (index of 52.6 in March 2026 versus a 2016 peak of 94.8) — that reflects a structural shift in corporate travel, not a crisis effect, and may act as a floor rather than a ceiling.
The BITRE Air Fares Index has an approximately 60-day reporting lag. The June 2026 release (covering April–May fares) will be the first to capture crisis-era pricing. The September 2026 release will give a fuller picture. AllFlights updates this page with each new BITRE quarterly release.
