How do you know if Turkish Airlines will raise or drop the prices?

A week ago i checked for prices from Boston to Venice and it was over $1400 and a few days later it dropped to $1115. The tickets are for June 29(ish, whenever it's cheaper) till July 15th.
How do I know if the prices will raise or drop? Should I buy it while it's cheaper or wait and risk it, hoping they will go lower…

Why does British Airways have such bad service?

I have to travel for my work and I have flown British Airways a few times and always encountered rude flight attendants. I asked a male flight attendant for a pen to fill out an immigration form, he refused and gave me a nasty state. Their food is bad, and the flight attendants just don't care.

I'm not the only one. Some of my work colleagues have also had issues with British Airways. And I've read a lot of online negative reviews about the company.

I think Emirates has the best service and British Airways is the worst

Is there an Airline just like Jet Blue?

I took a flight from San Antonio to Oklahoma City one time. The flight and SEATS were AWESOME! I loved how big and comfortable seats were! All the other airlines I feel claustrophobic, The front seat in right in my face, no arm room. I thought I was going to have a panic attack last time I left Vegas on Southwest Airlines.

Added (1). Jet Blue no longer flies out of San Antonio. The closest place I would have to drive is Houston to catch a flight on Jet Blue to Vegas.
