*error fare & business class* London to Caribbean, Central & South America in £500/£600s rtn

Update: guys, we're getting some reports that while the airline advertises Business Class tickets, most people are seeing 'Economy' as the ticket class on their reservation after booking. It could be a glitch on the airline's side. We highly recommend you take a screenshot to demonstrate the information seen on their website, in case this happens to you. In cases like this we typically see the airline either honour the fare or issue a refund. Some users have been told by Aeromexico support personel that they will try to honour these, but the airline has not yet confrimed this.
Incredible error fare here on *business class* routes to Central America & the Caribbean with Aeromexico!

These are not listed on Google Flights or Momondo, so it's best to go directly to the airline's website to find the fares and book. You'll find that the prices for their 'Premier' (business) class currently match their economy class fares on most dates throughout the year - including holidays. We've listed the best options we've spotted below, but this error fare seems to work on all routes by Aeromexico, so there may be others out there if you're planning a trip to the region :-)

As always, these can disappear any minute, so be quick if you're keen to make the trip!
Important: as with all error fares, do wait at least 2 weeks prior to booking any other non-refundable hotels, tours, etc. You can read more about error fares in my write up here.
