UPDATE: This deal has now expired. Congrats to those who got it!
British Airways is having another great First Class sale, this time putting routes from Prague (PRG) to either Mexico City (MEX) or Cancun (CUN) on sale for just ~$800 round trip.
This is a deal I recommend taking advantage of immediately and can be booked directly on AA.com or BritishAirways.com.
I would hold off on booking additional travel plans like hotels for now, but take advantage of this deal if you can work it into your travel schedule. Note that you MUST start in Prague for this price to be valid.
Flights on both British Airways and AA metal are available according to others that have booked it, though I’ve only been able to find BA metal myself. Apparently it’s also possible to route through LAX on the A380.
Good luck and happy travels!
