The "Executive Desk" gave me the following numbers.

BOTH numbers are DISCONNECTED.

Domestic: 313-234-6288
International: 313-234-6109

I've been stuck calling MP (during their business hours) at 605-399-2411, then asking to be transferred to international reservations. Then HAL answers and I have to punch in my MP number and then after screaming "Agent" at HAL a few times, he transfers me to the "Executive Desk."

I have tried the 312-364-1989 number. HAL answers, but the voice recognition and key recognition doesn't seem to work and I can't get it to transfer me anywhere properly (via telephone keypad or voice). It just transfers me to a line that gives a fast-beep.

I will try dialing the 880 area code in place of 800. Will report back.

When I tried the 800 area code from here in Thailand, I get a busy signal.
