Let's examine the given two-way table and identify the joint frequencies for each category of flights going either east or west for both Skyways and Yellow Jet airlines.

The table looks like this:
[tex]\[ \begin{array}{|c|c|c|c|} \hline & \text{East} & \text{West} & \text{Total} \\ \hline \text{Skyways} & 30 & 33 & 63 \\ \hline \text{Yellow Jet} & 35 & 34 & 69 \\ \hline \text{Total} & 65 & 67 & 132 \\ \hline \end{array} \][/tex]

We need to determine which of the joint frequencies (i.e., the combinations of airline and direction) has the highest number of flights.

The joint frequencies given in the table are:
1. Skyways going east: 30
2. Skyways going west: 33
3. Yellow Jet going east: 35
4. Yellow Jet going west: 34

To find which of these joint frequencies has the most flights, we compare the numbers:
- Skyways going east: 30
- Skyways going west: 33
- Yellow Jet going east: 35
- Yellow Jet going west: 34

From these comparisons, we see that the highest joint frequency is Yellow Jet going east with 35 flights.

Thus, the joint frequency with the most flights is:
Yellow Jet, going east
