Here is my reply from the 1K desk after I sent a letter voicing my concerns about, E+, MM, etc.
"...I appreciate your concern about the outcome of United and Continental merger. The merger has been approved, however until we receive the "joint operating certificate" from the DOT we will continue to operate as two separate airlines. We are excited to have begun the initial phases of a merger process that will last 12-18 months..."
The letter went on and did not address anything specifically.
