Can I Deduct Flights to See a Doctor? Medical Travel by Air Explained

When a medical condition requires you to travel by air to receive treatment, those airfare costs may be deductible as a medical expense. The IRS allows travel expenses for medical care — including flights — as part of the medical expense deduction on Schedule A. Here’s exactly when airfare qualifies, what rules apply, and how to document it correctly.

The Short Answer

Yes, flights to receive medical treatment may be deductible if: (1) the travel is primarily for medical care, (2) the care is not reasonably available locally, and (3) your total qualifying medical expenses exceed 7.5% of your adjusted gross income (AGI).

IRS Rules for Medical Transportation Deductions

The IRS allows deductions for transportation costs that are “primarily for and essential to medical care.” This includes all modes of transportation: driving (at the medical mileage rate), buses, trains, taxis, rideshares, and airplanes. Airfare is specifically mentioned in IRS Publication 502 as a deductible medical transportation expense.

The key requirements are:

Primary purpose must be medical. The flight’s primary reason must be to receive medical care. If you combine medical treatment with a vacation in the same trip, only the medical portion may qualify — and only if medical care is the primary purpose of the trip.
Care must be medically necessary. You must be traveling to receive treatment for a diagnosed condition from a licensed medical professional.
Treatment not available locally. While the IRS doesn’t explicitly require that treatment be unavailable locally, flights are most clearly justified when the medical care, specialist, or facility you need isn’t accessible near your home. Travel for care available locally is harder to defend.
You must itemize deductions. Medical expenses are deducted on Schedule A. You can only benefit if your total itemized deductions exceed the standard deduction ($15,000 single / $30,000 MFJ in 2025).
Total medical expenses must exceed 7.5% of AGI. Your airfare joins other qualifying medical expenses to calculate the deductible amount above the threshold.

Examples of Deductible Medical Flights

Flying to a specialized cancer treatment center (Mayo Clinic, MD Anderson, etc.) for cancer treatment
Traveling to a specialist in another state for a rare condition not treated locally
Flying for a second opinion on a serious diagnosis from a specialist who practices in another city
Traveling to receive an organ transplant or transplant evaluation
Flying to a rehabilitation facility for post-surgical recovery when the facility isn’t available locally
A parent accompanying a child to receive specialized pediatric treatment at a children’s hospital in another state

What About the Companion Who Travels With You?

If a companion travels with you for medical reasons — because your condition requires it — their transportation costs may also be deductible. The IRS specifically allows transportation for “a person whose presence is essential to receive medical care.” Examples include a parent accompanying a sick child, or a caregiver who must accompany a patient who cannot travel independently.

Note: the companion’s airfare may be deductible, but their meals are not.

Lodging During Medical Travel

If your medical trip requires an overnight stay, lodging expenses are deductible — but only up to $50 per night, per person. If you and one companion stay overnight for your medical care, the maximum lodging deduction is $100/night ($50 × 2 people). The lodging must be at or near the medical facility and the stay must be primarily for medical care — not comfort or convenience.

Meals during medical travel are not deductible, even if they’re part of an extended medical stay.

When Flights Do NOT Qualify

Combining medical travel with a vacation. If you flew to Miami for a vacation and also saw a doctor while there, the flight is not primarily for medical care and generally won’t qualify.
Wellness or elective trips. Flights to a spa retreat, wellness resort, or for elective cosmetic procedures don’t qualify as medical transportation.
Reimbursed costs. If your insurance, employer, or a health savings account covered the airfare, you can’t deduct it.
Travel for a family member who isn’t your dependent or spouse. Generally, you can only deduct medical expenses you paid for yourself, your spouse, or your dependents.

How to Document Medical Airfare

Thorough documentation is essential for airfare deductions — they’re larger than typical medical expenses and more likely to attract scrutiny. Keep the following:

Airline receipts or booking confirmations showing the cost and travel dates
A letter or documentation from your treating physician stating the medical necessity of travel to that facility or specialist
Appointment confirmations or medical records showing you received treatment at the destination
Hotel receipts for qualifying lodging (up to $50/night per person)
A brief written explanation of why treatment required travel (why local options weren’t sufficient)

Combining Airfare With Other Medical Travel Costs

Medical airfare is just one component of your total medical travel deduction. For a trip involving flights, you can also deduct:

Ground transportation to and from airports (taxi, Uber, shuttle)
Parking at your departure airport
Local transportation at the destination (to/from the medical facility)
Lodging at up to $50/night per person near the medical facility

All of these combine with your other qualifying medical expenses (prescriptions, doctor fees, medical equipment) to determine your total Schedule A medical deduction above the 7.5% AGI threshold.

Frequently Asked Questions

Can I deduct a flight to visit a specialist for a second opinion?

Yes, if obtaining a second opinion from a specialist in another city or state requires travel, those transportation costs are deductible. Second opinions are specifically recognized as legitimate medical purposes by the IRS. Document the appointment and the specialist’s credentials.

Does medical travel need to be domestic?

No — international medical travel can be deductible if it meets the same criteria: primarily for medical care, for treatment not reasonably available domestically, with proper documentation. International medical flights are higher value and require especially thorough documentation.

What if I used miles to pay for the flight?

If you used frequent flyer miles (for which you paid no cash) to purchase a medical flight, there is generally nothing to deduct — your out-of-pocket cost was $0. If you paid cash for the ticket and earned miles as a benefit, the cash cost is deductible.

Bottom Line

Airfare to receive necessary medical treatment can be a legitimate and substantial medical expense deduction. The IRS recognizes that serious medical conditions sometimes require traveling to specialists and facilities not available locally. Document thoroughly — your physician’s recommendation, the booking records, and the medical records from the visit — and add the cost to your other qualifying medical expenses when filing Schedule A.
