Airline tickets

Hello, my name is Alla Solodiak, I’m from Ukraine, but currently living in Greenville SC. Thursday of last week I had to live and go to Poland so I could bring my mom to United States since she had to leave her home country Ukraine and go to Poland to find a safe place due to the war in Ukraine. I’m now trying to bring her back with me since no one knows when it will be safe in Ukraine again. The tickets to bring her back with me has double It’s price, and the prices are keep going up. I’m desperate trying to get tickets so we can leave tomorrow or Thursday because I have my son back in USA. My mom is elderly and I don’t want to leave her as refugee back here in Poland. I would really really appreciate any help!!! And thank you so much!!!!
