I fly OAK/LAX, OAK/SAN, OAK/BUR frequently, more than one round trip per week. All of that business has gone to Southwest. So far, I'd estimate 6 round trips through the end of the upcoming week have gone to SW with many more to come. I realize many folks here think that the 500 miles are nothing worth getting upset about. However, for some of us who fly these routes frequently, the losses add up. I'd earn 1000 each way OAK/SAN connecting in LA, for example.
