Body
Refactor complex code to function If you have complex if statements try and wrap them up in functions. So <pre><code>(flightDestinations[i] == yourDestination && yourAirline == 'Any airline' && yourFare == 'Any price') </code></pre> could become <pre><code>function YourDestinationIsTheSameForAnyAirlineOrPrice(flightDestination, yourDestination, yourAirline, yourFare){ return flightDestination == yourDestination && yourAirline == 'Any airline' && yourFare == 'Any price'; } // And called from if if (YourDestinationIsTheSameForAnyAirlineOrPrice(flightDestinations[i], yourDestination, yourAirline, yourFare)) {} </code></pre> Rather than trying to decipher the if statement you have a function name telling you what it does. Use an object over multiple arrays Specific to your example I would also try and create a single flight object that contains the destination, time and airline. eg: <pre><code>var flight = { destination = "London", operator = "BA", time = "18:00 UTC", fare = "£239829" } </code></pre> This should make the code more readable than using multiple arrays. Example: <pre><code>destinationTime = flightTimes[i]; destinationOperator = flightOperators[i]; destinationFare = flightFares[i]; message += destinationTime + ' ' + destinationOperator + '. £' + destinationFare + ' '; // Using an object message += flight.Time + ' ' + flight.Operator + '. £' + flight.Fare + ' '; </code></pre> Return early Finally I would break out of the function as soon as possible. So use: <pre><code>if (yourDestination == 'Choose your destination') { displayMessage('Please choose a destination city from the Destination menu and then click Find flights again.'); return; } </code></pre> instead of an if...else. I personally find this more readable, so feel free to ignore this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
