Business Travel Trends 2026: Outlook, Spend & What's Changing
TL;DR: Global business travel spend is projected to reach $1.64 trillion in 2026, surpassing the 2019 pre-pandemic benchmark of $1.43 trillion (GBTA 2024 BTI Outlook). Average ticket prices are stabilizing after two years of inflation, AI booking tools are mainstream, and sustainability mandates are reshaping vendor selection. Bleisure, NDC adoption, and duty-of-care platforms are the four trends defining 2026 program design.
Drawing from 8+ years building AI-powered corporate travel platforms, the patterns that hold up in 2026 are not the loudest ones in vendor decks — they're the ones reflected in primary data from GBTA, IATA, and the U.S. GSA. This article distills the verified shifts, the spend numbers, and the program decisions travel managers should be making now.
1. Global Business Travel Spend Crosses $1.6 Trillion
The Global Business Travel Association's 2025 BTI Outlook projects worldwide business travel spend will reach $1.66 trillion in 2026, exceeding earlier projections as H1 2026 tracked ahead of forecast, with growth continuing at roughly 6–7% annually through 2028 (per GBTA 2025 BTI Outlook, published August 2025). Asia Pacific leads regional spend at approximately $720 billion, followed by North America at $410 billion and Western Europe at $345 billion. Notably, GBTA reports that 79% of corporate travel buyers expect their company's travel spend to increase in 2026 versus 2025, while only 8% anticipate cuts. The Bureau of Transportation Statistics (BTS) reported 853 million U.S. enplanements in 2024 — a record — signaling that business air demand is structurally back. For program owners, this means rate negotiations in late 2026 will favor suppliers unless volume commitments and data transparency are part of the deal.
2. Airfares Stabilize, but Hotel ADRs Keep Climbing
According to the U.S. Bureau of Labor Statistics CPI release for June 2026 (published July 11, 2026), domestic airfares fell 3.2% year-over-year as capacity expansion outpaced demand — a sharp reversal from the 7.4% jump recorded in 2023. IATA's June 2026 mid-year Global Outlook for Air Transport now projects 2026 worldwide passenger yields will decline 1.4%, steeper than its December 2025 forecast, as new lift entered service across North America and Asia Pacific in H1. Hotels are a different story: STR's Q2 2026 U.S. lodging update (published June 2026) trimmed full-year ADR growth to 2.6%, reaching approximately $160.75, while U.S. GSA per-diem rates for FY2026 rose in 302 non-standard locations, with the standard CONUS lodging rate at $110/night through September 30, 2026 (GSA, August 2025); FY2027 GSA rates publish mid-August 2026 and should be pulled into any Q4 policy refresh. For finance leaders, this asymmetry — flat air, rising lodging — should reshape policy caps. Programs that index hotel allowances to GSA rates by city are easier to defend in audits than flat-rate dollar caps, and they automatically adjust each October when GSA publishes new rates.
3. AI, NDC, and the Tooling Shift
The American Express Global Business Travel 2026 Tech Trends report (January 2026) found that 71% of travel programs now use AI-assisted booking recommendations, up from 34% in 2024. IATA's NDC (New Distribution Capability) adoption reached 36% of indirect airline content by Q2 2026 (IATA NDC Program update, June 2026), enabling richer fare bundles and ancillary visibility in corporate booking tools. The DOT's Final Rule on Ancillary Fee Transparency (effective October 2024) requires airlines to disclose baggage and change fees upfront — a tailwind for TMCs that surface true total cost. Platforms like Travel Code integrate NDC content with AI-driven policy enforcement so travelers see compliant options first, not last. The practical effect: leakage to consumer sites drops, and finance gets cleaner accruals. For deeper context on selecting tooling, see our Corporate Travel Booking Tool Comparison 2026.
Comparison: 2025 vs 2026 Key Business Travel Metrics
| Metric | 2025 Actual | 2026 Projection | Source |
|---|---|---|---|
| Global business travel spend | $1.54T | $1.64T | GBTA BTI Outlook 2024 |
| U.S. domestic airfare YoY change | +2.4% | −3.2% (June 2026 YoY) | BLS CPI, June 2026 |
| U.S. hotel ADR | $156.65 | $160.75 (+2.6%) | STR Q2 2026 Update |
| GSA standard CONUS lodging per diem | $107 | $110 | U.S. GSA, FY2026 |
| AI-assisted booking adoption | 52% | 71% | Amex GBT 2026 Tech Trends |
| NDC share of indirect airline content | 22% | 36% (Q2 2026) | IATA NDC Program, Q2 2026 |
| Buyers expecting spend increase | 72% | 79% | GBTA Buyer Sentiment, Q4 2025 |
4. Sustainability Moves From Pledge to Procurement
The EU Corporate Sustainability Reporting Directive (CSRD), in force since January 2024 with first reports filed in 2025, now requires roughly 50,000 companies to disclose Scope 3 travel emissions in audited filings (European Commission, CSRD Directive 2022/2464). In the U.S., the SEC's climate disclosure rule (final March 2024, partially stayed pending litigation as of April 2026) still drives voluntary reporting at large issuers. GBTA's 2025 Sustainability Index found that 64% of corporate travel programs now include emissions data in supplier RFPs, up from 38% in 2023. The practical implication for 2026: vendor scorecards weight verified CO₂ data, SAF (sustainable aviation fuel) procurement claims must align with IATA's CORSIA framework, and rail-first policies in Europe are quietly becoming the default for sub-500km trips. Travel managers writing new policy this year should align caps and approval rules with their finance team's CSRD or CDP submission format — see our Corporate Travel Policy Guide & Template 2026.
5. Duty of Care and Risk Visibility Are Non-Negotiable
International SOS's 2026 Risk Outlook (published January 2026) reported that 76% of organizations expect business travel risk to increase or remain elevated in 2026, citing geopolitical instability, climate disruption, and health threats. The ISO 31030:2021 standard for travel risk management is now referenced in over 40% of enterprise RFPs (GBTA RFP benchmarking, 2025). Programs are responding by consolidating booking data with real-time traveler tracking and pre-trip risk scoring. For background and a framework, see our Duty of Care in Corporate Travel 2026 guide.
6. Bleisure, Long-Stay, and Policy Modernization
Expedia Group's 2025 traveler value report found 56% of business travelers extended at least one trip for personal leisure in the prior 12 months. Companies are formalizing what was informal: clear approval rules, expense splits, and insurance coverage for the leisure portion. The IRS Publication 463 (revised 2025) remains the governing U.S. document for what's deductible when business and personal travel mix — predominant business purpose still rules. For policy drafters, see our Bleisure Travel Policy Guide and the broader Corporate Travel Management Guide 2026.
Frequently Asked Questions
How much is global business travel spend expected to reach in 2026?
GBTA's 2024 BTI Outlook projects $1.64 trillion in global business travel spend for 2026, up from approximately $1.54 trillion in 2025. Asia Pacific is the largest regional market, followed by North America and Western Europe.
Are business airfares going up or down in 2026?
Mostly flat. The U.S. BLS CPI (March 2026) shows domestic airfares rose just 1.8% YoY, and IATA's December 2025 outlook forecasts global passenger yields will dip 0.6% as airline capacity expands.
What is NDC and why does it matter for corporate travel in 2026?
NDC (New Distribution Capability) is IATA's XML-based airline distribution standard. It enables richer fares, branded bundles, and ancillary visibility inside corporate booking tools. As of Q1 2026, NDC represents over 30% of indirect airline content per IATA's program update, meaning TMCs without NDC-enabled platforms are increasingly showing incomplete inventory.
How are sustainability rules changing corporate travel programs?
The EU CSRD requires large companies to disclose Scope 3 travel emissions in audited reports (Directive 2022/2464, effective January 2024). GBTA's 2025 Sustainability Index found 64% of programs now require emissions data in supplier RFPs. Expect SAF claims, CO₂ reporting, and rail-first policies for short hauls to become standard scoring criteria.
What should travel managers prioritize in 2026 budget planning?
Three things: (1) index hotel caps to GSA per-diem rates rather than static dollar amounts (GSA FY2026 standard CONUS rate is $110); (2) negotiate hotel rates aggressively given the 3.1% STR-projected ADR rise; and (3) require NDC, AI-policy enforcement, and ISO 31030-aligned duty of care from any TMC or platform under consideration.
Is AI replacing travel agents in corporate travel?
No — augmenting them. The Amex GBT 2026 Tech Trends report shows 71% of programs use AI-assisted booking, but human agents remain critical for complex itineraries, disruption rebooking, and VIP service. The shift is toward AI handling 80% of routine transactions so human expertise concentrates where it adds the most value.

Mid-2026 Update: What H1 Actuals Confirm
Two new mid-year datasets reinforce the trends above. ARC's July 2026 Corporate Travel Monitor (published July 9, 2026) shows H1 2026 U.S. corporate air ticket volume up 4.3% year-over-year, with average corporate ticket price essentially flat at $754 (versus $761 in H1 2025) — a volume-led recovery rather than a price-led one. Separately, GBTA's Q2 2026 Business Travel Recovery Poll (June 2026) found 82% of travel buyers now report their 2026 program is meeting or exceeding pre-pandemic activity levels, up from 74% in the Q4 2025 poll. For 2027 RFPs being scoped this fall, H1 2026 actuals are the strongest bargaining evidence for volume-based rate negotiation with hotels and airlines — the direction of ADR softening (Section 2) and yield decline (IATA June 2026) both favor buyers with credible pipeline data.
