Is there a form I need to fill out when flying with Qatar Airways back to the UK?

Travelers flying back to the UK on Qatar Airways have recently received notifications about filling out a specific form prior to check-in at the airport. Users in the forum shared their experiences, with some stating that they filled it out but were not asked to show it at the check-in desk, while others reported being asked for it. It appears that this form is not universally mandatory, and requirements may vary by travel date and destination. Overall, many noted the quick nature of completing the form and considered it somewhat redundant. Recent travelers suggested being prepared to fill it out, though experiences with enforcement seem mixed.
