I live near Austin but have to be in Dallas for work 18 days per month so I rent a place there. Can I deduct the cost of the Dallas rental?

I am a Flight Attendant for a major carrier and my Base is Dallas, Austin as Satellite but I can never be awarded trips to/from Austin as I’m too junior with the company. Therefore I need to be in Dallas for reserve 18 days per month so I l’m forced to rent a place there. Of course I’m not reimbursed by the company. Can I deduct the cost of my Dallas rental? Thanks!
