I booked a leg of a flight for a vacation I planned with Frontier. A week after booking, my Grandma who had been sick for awhile received a stage IV cancer diagnosis and was given 3 weeks to live. I called Frontier to explain the situation and was also told that the economy ticket is non-refundable, no matter the circumstances. I basically felt like they were lecturing me that I should have bought the higher priced classic tickets or travel insurance. I guess this is how they keep their ticket prices lower, by not giving a crap when people have unforseen tradgedies. Business is business, but I personally will NEVER fly Frontier again. read full review »
