Overview of the app's screens, including check-in, flight overview, departure timeline, and boarding pass.

People who fly for work travel on tight schedules: in for a conference, out the same week. The flight is rarely the hard part. The hard part is the hours around it, and knowing when each one begins. This app, designed for Delta's frequent business customers in Singapore, takes that responsibility off the traveler.

The challenge

Most airline apps are built around the booking. They show a flight number, a gate, and a departure time, and leave the traveler to work backward from there. When should I leave? How long will security take? Is there time to drop a bag? For someone who flies every other week, these small calculations add up to a constant, low-level strain.

The approach

We designed the app around the traveler's clock instead of the airline's. Every screen answers one question: what should I be doing now? The itinerary becomes a sequence of moments, each with a time and a duration. The car and the hotel are already arranged, so the traveler follows the plan without having to build it.

The interface is dark, quiet, and legible at a glance. One accent color marks the single action available on each screen. Large numerals carry the facts that matter in an airport: terminal, gate, seat, time.

The trip at a glance

Two weeks out, the app shows only what is settled: route, dates, times, terminal, and gate. What is still open, the seat, is marked plainly, with a note on when it can be resolved.

One action at a time

At twenty-four hours, the same screen changes its purpose. The open question becomes a single button: check in.

Choosing a seat

The seat map places the cabin section on the aircraft, then shows availability in three states. Selecting a premium seat states the price before the traveler commits, and the button confirms the exact seat.

Baggage, stated plainly

Allowances and fees are listed as simple switches. What is included comes first; what costs extra is priced beside its toggle.

Confirmation

Check-in ends with a short receipt: bags, reference number, and seat. Nothing else is asked of the traveler.

The departure timeline

This is the center of the product. The day of travel is laid out as a single line, from getting ready at home to departure. Each step has a start time and a duration: the ride to the airport, bag drop, security, the walk to the gate. A marker shows where the traveler is now. The app says when to get up and when to leave, and the traveler never has to count backward from a boarding time.

Boarding pass

The boarding pass is one tap from the timeline and reverses the palette, so it reads clearly at arm's length and under a scanner.

In the air

Once airborne, the app shifts to the two things a traveler wants to know: where the aircraft is and how long is left. A second view gives altitude, speed, and distance in both imperial and metric units.

The app asks very little of the traveler. It tells them the next thing to do and the time to do it.
