One thing worth mentioning with Starlux is that prior to the chat, I had submitted the feedback form with my preferred seat choices. Never received a response.

Eventually decided to try the chat, spent 2 hours waiting and the first thing the rep says you already have so and so seats assigned 😑

Definitely recommend using the form to save time but no way to know it's been recieved/actioned without a call/chat if they don't reply..
