Even there, with the things that Delta has started this year (Triple EQMs on New York-Chicago, Double EQMs out of BNA/STL/RDU/PIT), only United/American matched the NYC-CHI (you'd think CO could have matched out of EWR if they really wanted to, even though the rest were out of LGA) - and UA only limited to residents of WI/IL/IN/CT/NJ/NY, and only AA has matched the BNA/STL/RDU/PIT, with UA/CO staying out of that one.
