Agoda is a pain because often they'll have the lowest fare which doesn't include checked baggage. I gave up on airfares with Agoda because it's too inconsistent. They should stick with hotels, they're good at that!

I won't be filing a tax return for 2024 and I'll wait for the tax inspectors to come bashing my door down! 😂
