What is distinctive about this configuration
- 48-seat Economy Plus variant (this slug, the 20J / 159Y configuration) vs the 45-seat Economy Plus variant (ua-39m-2), both otherwise identical 20C/179 total configs
- Row numbers 16-19 skipped entirely, a distinguishing numbering quirk vs UA's 737-800/900 fleet
- Highest row number (39) despite total seat count similar to 737-900ER (73C/73L, also 179 seats) due to the row-skipping convention
Where this comes from
Every row above is researched against published cabin plans for this operator and then checked against live availability. Where a figure is not known it says so rather than being estimated, which is why some pitch cells read "not recorded" instead of carrying a number we would not defend.
Seats abreast and seat pitch are defined in the glossary, alongside cabin layout.
