We had an early morning flight and arrived to our assigned gates to see a ghost town. Upon verifying the gate, we discovered it was changed from D gates to E gates in LAS, causing us to have to haul ass to get to our gate on time. There was zero communication about this change from Frontier via email or via their app. In this day & age, most people are not visiting ticket counters, so this is not only an oversight on Frontiers last, but it’s also hugely embarrassing that they can’t communicate with their customers.
