Pretty much the same. Both initially online forms which can be submitted for a return QR code, this code has the same information as the printed version and has the advantage of confirming your previously submitted electronic form. Using the printed and written form only will slow down your exit from the airport whilst they log your details into the central computer system. The QR for me took less than a second for me to be let through, you can either use the QR from your phone screen or print it out.
All the Govt promised checks before being allowed to fly from Manchester airport like temperature scan etc and revised boarding procedures along with sanitizing the aircraft, didn't happen. Told to go straight through to security then board when told, usual boarding free for all whilst the arriving passengers left from the rear of the aircraft. Spain was much better organised with temperature scans etc and not letting anyone inside the arrivals area, carpark only. Móstoles where I am, is currently around 40c day after day and sleep is not easy.
