Correct on that, however, I get full Delta miles including elite credit! And those transcon JFK-LAX/SFO/SEA trips add up fast esp a I go to LAX 5-6 times a year. Again, I know it's not at all a perfect solution and I definitely want to stick with CO because in most cases they have been very good to me, however temptation is very strong, esp since my elite upgrade chances seem to continually be dropping (even when attempting to use miles)!!!!!
