The interaction begins with a minimal flight map showing a route, with a collapsed boarding pass card at the bottom displaying only the airport codes. Dragging or scrolling the card upwards smoothly expands it into a full boarding pass bottom sheet. As it slides up, additional flight details, a barcode, and a 'Check in' button are progressively revealed. The transition features a natural, springy settling effect once the sheet reaches its fully expanded state.
