← Back to work Case Study — Citi × American Airlines

Credit card ads that live inside the booking flow

Rather than interrupt the AA.com booking journey with a banner, the AAdvantage card offer was designed as a native placement inside the flight-booking experience itself — and it became the single biggest driver of card acquisitions in the partnership.

Client

Citi × American Airlines (AAdvantage co-brand)

Role

Creative Director, UX/UI — Citi, 2025

Type

Native digital placements, flight-booking funnel

Impact

~90% of AAdvantage Platinum card sign-ups

The AAdvantage card offer — statement credit, bonus miles, and pricing — placed natively inside the AA.com trip summary page
01 — Problem

Reach travelers at peak intent, without breaking the booking flow or cheapening either brand.

Credit card acquisition is the growth engine of the Citi–American Airlines co-brand partnership. The challenge was reaching travelers at their moment of highest intent — mid-booking — without interrupting the flow or feeling like a bolt-on ad.

02 — Strategy

Native placements, tuned through rounds of qualitative testing.

I led the creative, testing, and optimization for these placements as Creative Director, UX/UI at Citi, with a team of designers and copywriters working cross-functionally with marketing, product, legal, and tech — and with American Airlines reviewing, approving, and implementing every placement on their side.

  • Designed the card offer as a native placement woven directly into the trip summary and passenger details steps of the AA.com booking flow — not a banner interruption
  • Refined offer hierarchy (the $300 statement credit + 40,000 bonus miles), card art, and contextual timing through rounds of qualitative, focus-group-style testing rather than live A/B measurement
  • Folded in qualitative feedback that aligned with business priorities and what legal would clear from a copy standpoint, balancing persuasion with a heavily regulated approval process on both the Citi and AA sides

Creative direction, UX and design by my team at Citi; American Airlines reviewed, approved, and handled the final coding and implementation on AA.com.

03 — Impact

The highest-converting card acquisition surface in the partnership.

The AA.com booking flow placements became the dominant acquisition channel for the AAdvantage Platinum card — most sign-ups for that card now originate from a direct click on these ads, inside the booking path itself.

~90%

of AAdvantage Platinum card sign-ups trace back to this placement, directly from the AA.com booking flow
