Last scan's sector-wide recovery cooled off, and two names re-broke the trend they had just fixed. Southwest ($LUV) and American ($AAL) — the same pair that broke down two scans ago and then fully recovered to strong-up last scan — both slipped back to a weak-down trend classification this scan, the third flip for this pair inside this cluster's recent history. RSI eased across the board even for the names holding their structure: Delta ($DAL), United ($UAL), $JETS, and Alaska ($ALK) all remain strong-up, but momentum decelerated everywhere except Delta, which posted the sector's best weekly gain. American still carries the sector's deepest 30-day decline, and it widened further to -15.87%.

Data as-of 2026-07-31 close for five of the six tickers (UAL, LUV, JETS, AAL, ALK); Delta's ($DAL) latest bar is dated 2026-07-30, one session behind the rest of the group — treat its numbers as a session stale relative to the others. All numbers from precomputed summaries/airlines.json. Comparison scan: 2026-07-28-airlines (2026-07-28 close).

RSI eased across the board this scan after last scan's sharp double-digit gains. Delta's RSI came in at 56.4, United's at 51.2, and both remain a step down from where they closed two sessions ago — though Delta's own weekly print (+8.08%) was the best in the sector, its 30-day change also slipped back to -5.18% from -3.84%. JETS and Alaska held their strong-up trend classification but both decelerated on the week (JETS +3.92%, down from +4.42%; Alaska +2.86%, down from +6.93% — the sector's best weekly print last scan).

The more notable move is structural: Southwest and American, the two names whose trend broke down two scans ago and then fully recovered to strong-up last scan, both slipped back to weak-down this scan. Southwest's RSI eased further to 42.5 and its 30-day change worsened slightly to -10.9%. American's case is more mixed — its weekly print actually improved to +5.46% (among the best in the sector this scan), yet its trend classification still downgraded, and its 30-day change widened to -15.87%, still the deepest decline in the group. Alaska remains the sector's furthest name from a 52-week high at -27.98%, a gap that widened again this scan even with its trend intact.

• Delta: RSI 59.9→56.4 (eased), trend unchanged (strong-up), 7D +5.6%→+8.08% (best weekly print in the sector this scan), 30D -3.84%→-5.18% (slipped back), 52wkHi -6.59%→-7.41% (widened slightly). Note: this reading is dated 2026-07-30, one session behind the rest of the sector.
• United: RSI 55.9→51.2 (cooled), trend unchanged (strong-up), 7D +5.16%→+2.59% (decelerated), 30D -8.45%→-10.21% (worsened), 52wkHi -10.81%→-12.57% (widened).
• Southwest: RSI 45.6→42.5 (eased further), trend re-broke strong-up→weak-down, 7D -4.89%→-0.24% (still negative but less so), 30D -10.25%→-10.9% (worsened slightly), 52wkHi -15.97%→-18.4% (widened).
• JETS (ETF): RSI 56.9→52.4 (cooled), trend unchanged (strong-up), 7D +4.42%→+3.92% (roughly steady), 30D -3.69%→-5.87% (worsened), 52wkHi -6.24%→-7.95% (widened slightly).
• American: RSI 48.9→48.5 (roughly flat), trend re-broke strong-up→weak-down, 7D +0.52%→+5.46% (improved despite the trend downgrade), 30D -14.29%→-15.87% (worsened, still the sector's deepest decline), 52wkHi -18.25%→-18.73% (widened slightly).
• Alaska: RSI 54.4→51.0 (cooled), trend unchanged (strong-up), 7D +6.93%→+2.86% (decelerated from the sector's best weekly print last scan), 30D -6.39%→-7.41% (worsened), 52wkHi -26.21%→-27.98% (widened, still the sector's widest gap).

RSI (Relative Strength Index) gauges how aggressively a stock has been bought or sold over roughly the past two weeks, on a 0-100 scale — under 30 signals an oversold, potentially undervalued stretch; over 70 signals overbought, extended risk; readings in between are neutral. The color icons below track that scale: green marks oversold/healthy, yellow marks neutral, orange marks approaching overbought, red marks a breakdown or extreme overbought reading. Trend reflects a stock's structural direction based on its moving averages (strong-up, weak-up, weak-down, strong-down); vs SMA20 shows how far price sits above or below its 20-day average; 52wkHi shows the distance below the stock's own one-year high — the closer to zero, the closer to a new high.

DAL, UAL, JETS, ALK — STRUCTURE HOLDS, MOMENTUM COOLS: All four names kept their strong-up trend classification, but RSI eased in every case and weekly gains decelerated from last scan's pace (except Delta, whose weekly print actually accelerated to +8.08%, the sector's best this scan — though that reading is a session behind the rest of the group). United's 30-day change kept worsening (-8.45%→-10.21%), and Alaska's distance from its 52-week high widened again to -27.98%, still the sector's widest gap.

LUV AND AAL — THE TREND BROKE BACK DOWN, THIRD FLIP IN THIS CLUSTER'S RECENT HISTORY: Southwest and American had broken down, then fully recovered to strong-up last scan; both slipped back to weak-down this scan. Southwest's case is straightforward deterioration — RSI eased further, weekly print still negative, 30-day change still worsening. American's is more mixed: its weekly print (+5.46%) was among the sector's better prints this scan even as its trend classification downgraded, and its 30-day change (-15.87%) remains the sector's deepest decline, having widened from -14.29%.

Does the Southwest/American trend break hold this time, given it has now flipped three times across this cluster's recent scans — or does it reverse again next scan the way it has twice before? Does American's 30-day decline, still the sector's deepest at -15.87%, stop widening even as its weekly print improves? And does Delta's data catch up to the rest of the sector next scan, given it's currently reporting a session behind the group?
