I don't know what to call this. Also please nicely tell me if a similar topic has been posted, so I could delete this one.
On routes like ATL to LGA, I see prices trop as low as 30 on a route that cost around 140$, when the base price is higher, I think a restriction on how low your price can get would help prevent this as its impossible to start a smaller airline, especially in R0 and R1 because of this. I would like a way for this to get fixed!
