Rachel Dube's home airport is Newark Liberty International Airport.Rachel Dube. Rachel Dube took a 20-hour flight with United Polaris business class. She says the service was amazing, and the seats were comfortable. Dube says the flight went very quickly and she would fly United's Polaris business class again. While I've always had a love for international travel, the pandemic really sparked my love of aviation.I splurge on some flights, but I'm also a big fan of using points and miles and finding flight deals.
