Tax Year Prior to 2020: Would buying plane tickets to and from a job be a travel deduction

[KarenL2]

Yes, but only if it's a temporary work location related to your current job.  For example, if your employee sends you on a business trip, it is deductible if not reimbursed by your employer.

If you are an employee receiving a W-2, they would be Unreimbursed Employee Business Expenses that goes onto Schedule A Itemized Deductions. If you don't normally itemize and use the Standard Deduction, then it may not benefit you unless your expenses are high enough.  Also, only the amount over 2% of your Adjusted Gross income will go onto the Schedule A.

Travel, Per Diem, and More
