terrible service agent made me miss my flight by mixing up my flight info then didn't own up to it..it took another agent to acknowledge what he did wrong then try to fix it but after hr wait it was too late for me to board
Tried to phone Frontier Customer Service. To no avail. NO CUSTOMER SERVICE # W as online 1hr. 26min prior to flight to check in. I didn't have access to my confirmation number. I/we went to online chat to no avail. Chat did not respond. Chatted again on way to airport via mobile this time. 1/2 later I finally received confirmation code only to be informed "check in closed." Frontier agents at check in counter REFUSED to check me in & call up to gateeven though/when Flight was delayed 3 hours.
horrible customer service and fees
crazy expensive for bags
they charge for carry on.
Paying for baggage is trash. I should have stayed with Southwest
Paying for a carry-on bag is ridiculous
