I agree that it is not this big of a change but I also find it nitpicking from Frontier's side. So they still give you 2 bags but why bother taking the rest away. I care less about the TV but I try to usually get 2 award seats for my wife and son and then seat selection ahead of time is very important with a 3 year old.
I doubt they save this much money (6$ for TV, seats are free for them anyway) and then why bother offending customers.
If they take the bags away then I can at least see that they get additional revenue but TV and especially seats (free from them anyway) is nitpicking.
