thank you OP for posting this!
Just managed to book two tickets for me and my partner,
on Lata m UK website, searched from scratch..
paid with PayPal and confirmed immediately like normally would,
chose seat before paying, and the the page with code and documents show up right after payment.
email as well
now the only thing is to decide what to do with the other possible ticket I booked earlier,
it was the Lata m rest of Europe website
went in via gf link, paid With credit card and payment taken, confirm of card payment (3rd party page) showed.. But then website crashed..
no email or anything regarding that booking.
hope we can travel by then.
