Hey there! Prepare for a simple trip at Terminal 1 if you're traveling Frontier from SFO. Although checking in is simple, luggage fees can mount up. Give yourself more time because security might be delayed. The dining selections at the Frontier Airlines SFO Terminal are mediocre at best. Although seating is limited, boarding is often swift. It's a passable experience if you don't mind paying for extras and packing light. For the price, isn't it the most comfortable? difficult to defeat. Just be patient!
