MEXICO CITY, June 7 (Reuters) - Mexico's military-run

airline Mexicana will pay $750 million to Brazilian planemaker

Embraer ( ERJ ) for the acquisition of 20 aircraft, according to a

government presentation released on Friday.

Earlier this week, Citi analysts estimated the price of the

Embraer ( ERJ ) order by Mexicana at around $1.4 billion, but said the

carrier has likely received a discount given its size.

J.P. Morgan, meanwhile, estimated the price at closer to

$1.6 billion.
