United has round-trip flights from Houston (IAH) to Tampa or Newark (TPA/EWR) for $97-$111, NONSTOP. Flights vary depending on destination, between October to April. Holiday blackouts. Mostly Tuesdays, Wednesdays, or Saturdays. A few extended Weekends available. Origin/Destination reversible.
Note: United “Basic Economy” fares do not include a free carry-on bag. Only a personal item (like a small laptop bag) is free. Seats are randomly assigned for free prior to boarding. If you have the United MileagePlus credit-card, use the “free checked bag” perk.
Note: The personal item size on United flights is smaller (9-in/10-in/17-in) than Frontier or Spirit (8-in/14-in/18-in).
