If I was planning on buying and holding for at least 10 years, I'd buy every airline (Delta, United, American, Alaskan, Spirit, JetBlue) and Cruiseline (Carnival, Norwegian, Royal Caribbean). It could be several years before they are back to normal but there's no doubt they will be back. If anything I think they will come out of this stronger. People are going to be dying to fly and cruise after quarantine. Even if they don't think it will be safe for as long as 2-3 years, the demand for travel will surge back.
Live Nation as well...once it's safe to be in crowds again, every concert will be packed.
I might add Disney too. I was looking to buy tickets for next spring/summer and a TON of dates are already sold out. Packages for 2021 were just available to purchase today. Don't anybody underestimate the appeal of Disney. I'm a huge fan, and I admit their prices are absurd, but I can't wait to go back.
