UPDATE #11 @ 2103 UK time – It is quite unclear which airport Air Canada flight AC990 from Mexico City to Toronto will be diverting to. The only options currently are Tampico or Ciudad Victoria International Airport.
UPDATE #12 @ 2106 UK time – AC990 is getting closer to the border between Mexico and the United States, so there is the potential that it will divert to an American airfield potentially.
UPDATE #13 @ 2109 UK time – CONFIRMED! AC990 will be diverting to Houston in the United States, so they are going to limp the aircraft over there instead.
