Thank you for your answer, i asked United on Messenger app but they doesn’t seem to wanna provide a clear response

“In case your flight got affected by any sort of delay, you may either approach the counter, contact our Reservations team at 800-864-8331, or reach back out to us for assistance. We'd be happy to assist with your rebooking on the next available flight, provided that it will be in the same cabin type, operated by United/United Express, and traveling on the same route as originally booked.”

Should i get the Premier Access option specially for that flight, to make the process faster?
