On the rare chance that something does happen it wil be well before your arrival at the airport. Have no worries and enjoy BA!
OP is dealing with MX btw, not BA.
You experience was occured with UA, not MX. If UA wouldn't honor a mistake, being a major american player, it would be reported everywhere. Whereas MX is a foreign carrier, and also a rather small airline, different countries have different rules to protect customers, it may not even have the rule in Mexico.
