Airlines That Now Offer Unbundled Services

Airlines that now practice unbundled pricing for checkedin bags

1. United. Used to be $15 per bag now, the second bag costs $50. Second bag used to be $25.
   
2. Delta. First bag is free, second bag is a whopping $50.
   
3. Frontier. $15 and $25
   
4. Continental $15 per bag

The lone rider who has not unbundled baggage checkin fee is Southwest.

Delta's scheme of $0 for the first and $50 for the second is interesting. Their customer profile data over the years must dictate this steeper charge for the second bag. The question that needs answering are, why they chose to bundle the first bag.  If the passenger profiles of United and Delta are alike, shouldn't the Reservation Price (RP) be alike and hence both should charge similar pricing for first bag?
