It’s Spirit need I say more? Thank this little airline because without it the other airlines would raise their prices so much I wouldn’t be able to fly anywhere. It’s affordable and gets you where you need to go! I’m not flying to get a free bag of chips, y’know?

I really liked the personalized treatment at the MDE airport, where someone from SPIRIT received me at the entrance of the counter line to ask if the weight of my luggage was accurate or if I wanted a better seat, gave me a name tag for my luggage and walked me to the counter. Thank you.
