Just returned from Riviera Maya where we met up with friends who had travelled from London with Thomas Cook Airlines. We flew with Thomson, came home last Thursday and paid 765 pesos each to exit Mexico. We'd been advised it was 800 each before we left the UK but our holiday rep told us the price had gone down.
Discussing this with our friends tonight who flew home on Monday and they paid 900 pesos each! Did the price change over the weekend? Even more worrying is that they say they gave the money to a man who then appeared as cabin crew on their flight home. Just read the FCO website who warn that fake officials operate in some airports - have they been conned? You get no receipt for the money paid - just a passport stamp.
