Verdict: which one has fewer problems?

Across the latest 600 App Store reviews we collected, Southwest has the lowest share of reviews with a complaint (45%) and Delta the highest (78%). The biggest single difference is in bug complaints: 64% of Delta reviews mention them, vs 27% for Southwest. Each app's own biggest complaint theme: Delta, bugs (193 reviews); Southwest, bugs (81 reviews). Average star rating in the samples ranges from 1.76★ (Delta) to 2.98★ (Southwest). Time span of each sample: Delta 180 days (2026-04-26 to 2026-10-22); Southwest 22 days (2026-10-01 to 2026-10-22). Because Southwest's sample covers a much shorter period, a single recent update or outage weighs more heavily in its numbers. Samples that reach back many months (fewer reviews per day) show long-running issues rather than the effect of one recent update.
