You don't need to worry about how the slightly delayed scratch-offs can affect the items on your itinerary. If your schedule changes, you can request an Aeromexico undoing. In this case, you will preserve the original payment of the passage but be required to pay the price difference if your new flight is more expensive. Travelers on Basic or Value charges who are forced to Cancel Aeromexico Flight due to adverse weather conditions or governmental travel restrictions are eligible for a discount.
