Correct, pay is not one of the 40 words in the puzzle about travel. PASS is part of a bigger word, PASSPORT, that someone already guessed.

At the end of the 7 days, I will post the solutions here in the comments that come with the list of 40 words as well.

again I say... there's also the word PASS in the puzzle besides or passport see the line above the word "luggage" but I understand that even if words are present it doesn't count.

Understood. Yeah, there are probably several other words in there that do not count as well.

no problem. It looks like fun but it will be hard for me to join. It's a lot of scrolling to see the other entries.

It can be challenging if you're coming in on mobile. The trick is to get here early before anyone else, then it's easy to guess.
