Beware of Hotwire. Hot wire is tricky and does not offer refunds for so-called "Hot rates."
Even if you try to cancel within hours, they will only offer you so-called "Hot cash" which you can ONLY use on "Hot rates" for a year. And trust me, you will likely not find a "Hot rate" for that period if you need it and never use your so-called "Hot cash." What a "Hot mess!"
