I was contacted about a change to the time of one of my flights, and was asked to reply to the email to confirm my acceptance of the changes. I took the opportunity to ask a question when I replied. The customer service rep Liam Johnson didn't reply to my question in his response, so I asked it again, plus one more question. This time he replied to my first question but not the second. So I left it at that! I'll check directly with the airline. He responded pretty quickly but could do with reading the customer emails fully and replying in full at first go, to save customer frustration (we don't like being ignored).
