Sure, I can help you with that!

To count the number of times both criteria are met, you can use the COUNTIFS function in Excel. Here's how:

1. Select the cell where you want to display the result.
2. Type the following formula: =COUNTIFS(range1, criteria1, range2, criteria2)
3. Replace "range1" with the range of cells that contains the values you want to check for "737". Replace "criteria1" with "737" (without quotes).
4. Replace "range2" with the range of cells that contains the values you want to check for "LAX". Replace "criteria2" with "LAX" (without quotes).
5. Press Enter to see the result.

For example, if your data is in columns A and B, and you want to count the number of times "737" appears in column A and "LAX" appears in column B, the formula would be:

=COUNTIFS(A:A, "737", B:B, "LAX")

This will give you the count of all the rows where both criteria are met.
