Here is a screenshot from Google Flights:
I've encountered similar scenarios multiple times. Google is claiming that one can book these flights for 186 USD with a travel agent. I've checked a few travel agent websites (like kayak, momondo, skyscanner, expedia, and some others) and this ticket is not available anywhere. Is Google Flights' claim about the existence of a travel agent who is selling this ticket for 186 USD wrong, or does such a travel agent actually exist and I just failed to find it?
The question is not about this particular ticket (though if someone can find a proof that the $186 price is legit, it would be neat), but rather about whether I should trust Google about agent's prices in general.
