100% and people just do not understand customer service reps just do no have the time to spend 'top quality time' reading through multiple complaints in the same email - in the same manner if someone writes up a rant on this forum, if it's more than 3 paragraphs, I just stop reading. Less is more.

People naturally assuming ranting is more likely to get some attention. I find that perplexing. I had a US guy write a huge email to us with multiple screengrabs simply as he couldn't get a license working. All he had to do was copy and paste it carefully. Yet he must have written a 500 word rant about it with all sorts of accusations.

Keep things basic and simple. Focus on something specific. Trying to accuse BA of potential racism won't get any compensation. I've had issues with my passport before with my specific US visa. It happens. When I check-in sometimes I get queried about the visa info and whether it's valid and if I have an ESTA (no, as I have a visa...!) etc etc. It's their job to query the specifics as they are responsible if they let you through and you didn't have a valid visa or ESTA etc.
