This section on their policy is needlessly ambiguous. It's very clear from the first line that you are allowed to make a stand by request 24 hours before the flight leaves, but the second line muddies it up with the "12 hours from when you are making the request." leading to agent confusion. It should be "12 hours from your original scheduled flight."
