Hello! I had a passable experience with Frontier Airlines LGA Terminal Although it's a simple setup, it works well. Self-service kiosks made it easy to check in, and security was speedy as well. However, the gate area was crowded, making it difficult to find a seat. Bring your own food and entertainment because there aren't many restaurants or stores. The staff wasn't too attentive, but they were polite enough. The terminal is simple but effective, reflecting the airline's low cost. It's completely possible if you know what you're getting into.
