If you work for an airline, your payslip rarely tells a simple story. Basic salary is only part of the picture - flight pay, duty allowances, commission on in-flight sales, overtime and overseas allowances can make up a large share of what you actually earn. The good news: airline staff can absolutely get competitive mortgages, and the right lender may count far more of your income than your bank first suggests.
Key takeaway: Most lenders will use 100% of your basic salary, but treatment of flight pay and allowances varies hugely - some count all of it, some half, some none. Choosing the right lender for your pay structure often matters more than the headline rate.

Why is airline pay tricky for mortgage lenders?
Mortgage affordability checks were designed around a fixed monthly salary. Airline pay doesn't work like that. A typical aviation payslip might include basic salary, hourly flight or duty pay that varies with your roster, sector pay, commission, overnight allowances and per diems, plus seasonal overtime.
A lender that doesn't understand this mix may assess you on basic salary alone. For cabin crew in particular - where basic pay can be modest and variable pay makes up a significant share of take-home earnings - that can cut a borrowing figure dramatically. For pilots, the challenge is different: income is strong, but new first officers on probation, recent airline moves, or long-haul allowance structures can complicate how it's assessed.
How do lenders treat each part of airline pay?
Basic salary
Almost all lenders use 100% of contractual basic pay. This is your foundation - everything else is negotiated on top.
Flight pay and duty allowances
This is where lenders differ most. Some will use 100% of regular flight or duty pay evidenced on your payslips, others cap it at around 50-60%, and a few exclude it entirely. Three months of payslips is typically sufficient for most lenders - and if your last P60 backs up that your current earnings are consistent with previous years, this unlocks more options.
Commission and overtime
In-flight sales commission and voluntary overtime are usually treated as variable income. Regularity is what counts: a steady figure across your recent payslips, supported by your P60, is far more usable than occasional spikes.
Per diems and overnight allowances
These are the hardest to use. Because per diems are intended to cover food and expenses while you're away, many lenders treat them as expense reimbursement rather than income - though a minority will consider regular, contractual allowances. Don't assume they're lost; assume they need the right lender.
Foreign currency pay
If part of your package is paid in dollars, euros or another currency, a smaller pool of lenders can help, and they will usually reduce the amount they count to allow for exchange rate movements. It's a specialist area, but far from a dead end.
Here's the picture at a glance:

Tip: Keep your recent payslips and your latest P60 together. Most lenders only need your last 3 months' payslips, and a P60 showing your current earnings are in line with previous years gives underwriters confidence that your variable pay is the norm, not a one-off good patch.

How much could you borrow as airline staff?
Because lenders differ on both income multiples and how much variable pay they'll count, two lenders can reach very different figures for the same person. Try the calculator below - enter your basic salary and your typical annual flight pay, commission and overtime to see how the range moves.
[[calc:borrowing]]
Standard borrowing sits around 4.5 times income, with some lenders stretching to 5 times or more for stronger earners - which is why getting your variable pay counted properly can be worth tens of thousands of pounds of borrowing power.
Does your role make a difference?
Pilots
Industry salary data puts UK first officers anywhere from around £40,000 to £90,000 or more, and captains well beyond that, so affordability is rarely the issue. The pinch points are typically training debt, probation periods after joining a new airline, and making sure long-haul allowances are assessed fairly. Higher earners may also access enhanced income multiples with some lenders.
Cabin crew
Cabin crew applications stand or fall on variable pay. With base salaries often in the low-to-mid £20,000s and meaningful flight pay and commission on top, the gap between a lender using 0% and 100% of your variable income is enormous. Many cabin crew are also first-time buyers, where low-deposit schemes and enhanced multiples for newer buyers can help too.
Ground staff and engineers
Ground operations, engineering and airport-based staff usually have a steadier pay pattern - base salary plus contractual shift and unsocial-hours allowances. Contractual allowances are widely accepted, so the job here is simply evidencing them properly and picking a lender that uses them in full.
Case study: An illustrative example of how lender choice changes the outcome.
Situation: A cabin crew member with a £22,000 basic salary and roughly £9,500 a year in regular flight pay and commission was told by her bank she could borrow around £99,000 - it had used basic salary only.
What we did: We evidenced her recent payslips alongside her latest P60, which confirmed her variable pay was consistent year on year, and placed the application with a lender that counts it in full.
Outcome: The lender assessed income of £31,500, supporting borrowing of around £140,000 - a materially different house-hunting budget. Figures are illustrative; outcomes depend on individual circumstances.
What about probation, new contracts and seasonal work?
Aviation careers move around - new airlines, new bases, seasonal contracts. Lenders vary on all of it. Some accept a signed permanent contract from day one; others want you through probation. Seasonal or fixed-term contracts narrow the field but don't close it, particularly with a track record of renewals. If you've recently switched airlines on similar or better pay, many lenders will take a pragmatic view.
Good to know: A remortgage counts too. If you took your current mortgage when a lender would only use your basic salary, your fuller earnings picture may support better options when your deal ends - see our remortgage advice page.
How can airline staff strengthen a mortgage application?
Build the evidence before you apply: your last 3 months' payslips, your most recent P60, and your employment contract showing contractual allowances. Keep variable earnings visible in one bank account rather than scattered. Avoid gaps between contracts where possible, and if a move or promotion is coming, time your application around it. Above all, don't accept a base-salary-only assessment as the final word - it's usually the starting point, not the ceiling. Our mortgage advice team can review your payslips and match your pay structure to the right lender before anything goes near a credit check.

Frequently asked questions
Can cabin crew get a mortgage on a low basic salary?
Yes. The key is choosing a lender that counts your flight pay, commission and allowances. With consistent payslip evidence, many lenders will use some or all of your variable income, which can transform the affordability calculation.
Do lenders count flight pay and per diems?
Flight and duty pay is accepted by many lenders, at anywhere from 50% to 100%. Per diems are harder, as they're often classed as expenses - but regular, contractual allowances may be considered by the right lender.
How many payslips do airline staff need for a mortgage?
Three months' payslips is typically sufficient for most lenders. If your last P60 backs up that your current earnings are consistent with previous years, this unlocks more options for using your variable pay in full.
Can pilots borrow more than 4.5 times their salary?
Some lenders offer enhanced income multiples to higher earners, which can include experienced pilots. Eligibility depends on income level, deposit and the lender's criteria at the time - personalised advice is essential here.
Does a probation period stop me getting a mortgage?
Not necessarily. Some lenders will proceed with a signed permanent contract even during probation, particularly where you're continuing in the same industry. Others prefer to wait - a broker can tell you which is which.
