While in Mexico, I bought a ticket from Iberia “Mexico - Spain - Morocco”, in Spain there would be a transfer. A ticket was confirmed, I received a confirmation number. I purchased it from the website of Iberia using my bank debit card. The money was deducted from my account. No ploblem so far.
After 2 days I received an email from Amadeus titled “Your flight confirmation”. In was in plain text format. The first part of it re-confirmed the information of my flight. “Nothing interesting” - I thought. However, there was a note in the bottom to which I turned a blind eye.
