Use the airline that sold your flight: American, Delta or United. Republic's partner handles reservations, ticketing, seat assignments, changes and refunds. Republic operates the aircraft rather than selling and managing a separate Republic booking.
Republic follows the relevant American, Delta or United carry-on and checked-baggage policies. Its aircraft also have additional restrictions: sporting equipment must be no longer than 96 inches. Check Republic's restrictions alongside the ticketing airline's allowance instead of assuming one allowance for every Republic flight.
