Watch and — these are users who got past 'Find trains' and still didn't complete. Look specifically for where they pause on /passenger and what they do before leaving. The passenger details page has the longest dwell time for abandoners (4.7s median) and almost nobody in this group reached 'Continue to payment'.

Query PostHog filtering sessions by the returning user IDs who attempted 'Book a seat' across multiple sessions without completing — a group of repeat abandoners is already visible in the person-level data. Look at which step they exit on each attempt and whether it's consistent. If they're always dropping at the same page, that's your fix.

A dead_click was recorded on 'div#root' at / and a navigation loop was detected on 'northrail.uxsense.ai/' — both in the abandonment group. Watch (the exited session) to see if the homepage interaction failure is reproducible. If div#root is swallowing clicks, some users may never be getting their search submitted.
