How about this...  Using a slightly modified array that you posted, I came up
with this in about 10 minutes

<pre>I am working with the following data structure

<?php

$in = array(
  0 => array(
    0 => array('Flight Number', 'flight_number'),
    1 => array(
        0 => array('Timestamp Departure', 'timestamp_departure'),
        1 => array('Timestamp Arrival', 'timestamp_arrival'),
      )
    ),
  1 => array('Departure City', 'departure_city'),
  2 => array('Arrival City', 'arrival_city'),
);

print_r($in);

echo "\n\n";

$max_depth = 0;
$cur_depth = 0;
function max_array_depth($ar) {
	global $cur_depth, $max_depth;
	if ( is_array($ar) ) {
		$cur_depth++;
		if ( $cur_depth > $max_depth ) {
			$max_depth = $cur_depth;
		}
		foreach ( $ar AS $row ) {
			max_array_depth($row);
		}
		$cur_depth--;
	}
}

max_array_depth($in);

echo "Max depth of array is: {$max_depth}";

?></pre>
