1. Travelers get fooled by Spirit's unique pricing model.
It seems like they charge you for everything. Because they do. And once they do, you might as well fly on any other airline. You won't save any money.
2. General rudeness.
Spirit tries to save money everywhere. Including the salaries of their employees. And you get what you pay for.
3. It may take you 3-4 days to get to your destination.
Spirit is the only national airline that doesn't provide backup jets, or crew or have agreements with other airlines. This means that if your aircraft is unable to fly, you won't be going anywhere. This can (and often has) lead to travelers being forced to wait three or more days for the next available seat on a Spirit flight with little or no reimbursement for meals, hotel stays or rental cars throughout the days you're waiting for your flight.
Issue #1 can be overcome if you understand their pricing model and work within it.
Issue #2 is a pain, but travel is often a pain.
Issue #3, however, is a fundamental violation to the pact between an airline and a traveler. An airline has only ONE responsibility, that is to get you safely to your destination in an appropriate amount of time. And Spirit has repeatedly and without apology violated this pact again and again, week after week, month after month, year after year. This is not about a several-hour delay. This is about being forced to miss entire vacations, business meetings and family functions because Spirit doesn't care enough to get you there.
That is ... until this weekend! On August 8, 2015, we received information from travelers flying from both Minneapolis-St. Paul International Airport and from LaGuardia Airport that, after cancelling flights, Spirit was buying tickets on other airlines for the travelers who were supposed to be on those cancelled flights.
If this is the beginning of a new Spirit policy, this is BIG, BIG news. And if it's not a new Spirit policy, it's big news that, on at least one day in their existence, Spirit Airlines did the right things for passengers in at least two cities.
So, a rare kudos to Spirit! Please keep up the good work.
We will be watching and reporting on whether this policy continues.
UPDATE: It's two days later and Spirit is still stranding their passengers for three days at a time at airports across the U.S.
