It is because the opposing team also matters. You can raise ticket price if your opponent have many trophy (therefore a lot of fans), against weak teams you can't raise as much.
As CL opponents are stronger on average it is normal that you can charge a higher amount.
In cup it depends but later stages of the cup can raise more due to strong teams (with many fans) advancing.
I increased mine from 18 to 60 and still maxed out so I've put it upto 65 and see if there is a decrease.

I'm building my stadium as fast as it will let me, it's 13,000 right now, but is under construction for the next level, sadly you have to do all the other stuff before it will let you build again.
Level 18
17 league titles
14 cups

I needed not to tank. But for about 2 or 3 seasons, my now Level 28 team have to cut bonuses to nil and significantly slowed down buying players to leave the cash to build stadium. At that time, I need to carefully manage cash for re-signing out of contract players. Sometimes, I lacked cash to do any of them. I thought that my team will no longer be title contender again. But after the full stadium is built and Nordeus increased the competition prizes, I have no more worry about cash again.
My now level 20 team never have such problem. It build stadium quickly since low levels.
You should also play attention if your attendance have already met the maximum limit for your level. If this limit is reached, you can still gain 5% extra procession. But you should wait until next level that more fans can buy your tickets. In this situation, you may put building other facilities in higher priority.
There is a maximum attendance for each level. This is the maximum number of fans who can attend a match no matter how large your stadium is.
For example, say the maximum attendance for your level is 20000. After you build your stadium to 21000 seats, the maximum attendance is still 20000 but you can still get full 5% additional procession with this attendance. After you promote to next level, the maximum attendance may increase to or above 21000. Then you are possible to raise attendance to 21000 and get 5% procession. If your attendance is still 20000, you may only get 4% or less additional procession.
