The travel sites I saw blocked didn't fail because of GA blocking I believe, but they were depending on various other scripts. I believe they just had messy code that relied on callbacks from third party scripts -- some of which were blocked by uBlock.

Might be worthwhile finding a different online travel company, if they can't get this right I can't imagine what else they'll stuff up when you make a booking!
