Will I be sitting on the same plane as someone with the same flight code but different class?

I am travelling using United Airlines and I booked flights for myself and a relative, and wanted to ensure we were both physically sitting on the same plane. I checked the flight codes upon booking but realised afterwards that the flight codes were slightly different: mine was UA 179 K whereas my relative's was UA 179 W. The flight codes are the same (UA 179) but the classes are diifferent (K and W). Will this still mean that we will both be sitting on the same plane? (I have checked other details such as departure time, layover times, aircraft... and they're all pretty much the same). Many thanks.

United airlines booking classes can be seen here.
- K Deep Discount Coach
- W Discount Coach
These are different fares within the coach/economy section.

Does same flight number mean same plane?
Just because two flights have the same flight number doesn't necessarily mean that you'll have the same aircraft. The way to find out is by going on AA.com and then entering the flight number (1819).Can I get on the same flight as someone else?
Yes you can. Check-in online and select the seats so that you can sit together atleast one day in advance. Last time we traveled, I did buy 2 tickets separately for me and my wife.Do airlines sit you together?
When booking tickets online, many airlines charge extra to choose a specific seat, meaning that people have to pay more to guarantee sitting with their companion or group. If passengers choose not to buy specific seats they may still be able to sit together but it is not guaranteed.Can there be two flights with the same number?
Yes, the same flight number can be used to refer to multiple flights active at the same time. This happens fairly regularly if a flight is heavily delayed. The previous days flight may still be active the same time as the current days flight takes off.Do pilots always fly the same route and aircraft?
