Silver Airways looks golden to Tupelo airport to replace Delta Air Lines - The Washington Post

How can they buy a ticket on Delta.com If they are not going to be flying on a delta or delta connection flight? It looks like this is Delta's way of getting around the all jet service. I have not looked into it here in MSP but it would not surprise me if you can buy a ticket for great lakes on delta.com also. This makes me wonder if there is going to be a third tier of flying. Delta will do the very large cities and long flight the regional will do medium to large cites and the small prop regional will do the EAS flying saying they are not a connection or express but they get the benefit of buying their tickets on a majors website.
