missing first out of 3 connectioinflights
Hey, there I'm flying with Copa Airlines from Honolulu to Bogota on the 11th January. My flight connection is from HNL - LA 1h 30 min layover, LA - PTY 1h 20 min layover, PTY - Bogota. All flights are with Copa Airlines. I recently decided to leave the Islands sooner and go back to the mainland. So I'll first be in Las Vegas and take then the bus to LA so that I'll be there to catch my flight from LA to Panama(PTY) on the 1/11. My question is now if I have to inform Copa Airlines about my change of plans, if it costs me a lot of money, or if there's a way to cancel my first flight from HNL - LA without having to pay extra?
I would also love to know if I have to take care of my extra luggage myself or if the flight company does that since 1h 20 min seem to be little time to check in with baggage again. I never flew with Copa Airlines before and I appreciate every help.
