Every carrier in the group closed the week lower, and the RSI compression that started two scans ago hasn't stopped — the sector has now fallen from a mid-50s RSI band to the high-30s/low-50s. AAL is the standout casualty: it broke structure, downgrading from strong-up to weak-down trend, and posted the sector's worst week (-11.62% 7D) with its 30-day change flipping from +15.70% to -6.32%. UAL, JETS, and LUV all saw their 30-day changes flip negative or flatten as well, and ALK's regime was downgraded to outright downtrend. This is a settled EOW close, not an intraday print, and it lands the same week the Gulf ceasefire collapsed and strikes widened — a fuel-cost and route-risk backdrop worth watching even though nothing in this price data proves that link directly.

Data as-of 2026-07-17 close (all six tickers, current). All numbers from precomputed summaries/airlines.json. Prior scan: 2026-07-11-airlines (2026-07-11, data as-of 2026-07-10 close).

AAL — STRUCTURE BROKE: AAL ($14.98, RSI 39.0) is the sector's clearest casualty this week. Its trend classification downgraded from strong-up to weak-down, the first structural break in this cluster in recent scans. The 30-day change flipped from +15.70% (07-10 close) to -6.32% — a roughly 22-point swing — on the sector's worst weekly decline (-11.62%). It's now -20.28% from its 52-week high, versus -9.79% two scans ago.

MONSTER-TIER EXTENSION FULLY UNWOUND: DAL's vs SMA200 has now fallen in three straight readings: 34.9% (07-06) → 27.8% (07-10) → 21.8% (07-17). What briefly qualified as monster-tier extension in early July is gone. UAL's vs SMA200 sits at 10.5%, also down from the 21.2% flagged mid-month. The sector-wide froth that showed up as RSI 68-74 two scans back has fully drained.

UAL AND JETS — 30-DAY GAINS FLIPPED NEGATIVE OR FLAT: UAL ($115.41, RSI 41.0) had the worst single week among the majors (-8.4% 7D) and its 30-day change flipped from +11.89% to -2.46%. JETS ($30.46, RSI 44.7) followed the same pattern, 30D flipping from +10.77% to -1.74%. LUV ($48.08, RSI 50.9) held up best of the group — smallest 7D decline (-0.72%) — but its own 30-day gain compressed to roughly flat (+0.23%, was +9.35%).

ALK — STILL THE STRUCTURAL LAGGARD, NOW WITH A REGIME DOWNGRADE: ALK ($45.51, RSI 42.3) is -30.92% from its 52-week high, deeper than the -24.98% flagged last scan, and its regime classification is now downtrend (was a milder "up" trend two scans ago). The death cross remains unresolved. This is the third straight scan flagging ALK as the group's weakest structural name.

• All six carriers fell this week: DAL -3.68%, UAL -8.4%, LUV -0.72%, JETS -5.08%, AAL -11.62%, ALK -7.91% (7D).
• RSI compressed further across the board: from a 53.6-58.5 band (07-10 close) to 39.0-50.9 (07-17 close).
• 30-day changes flipped negative or flattened for four of six names: UAL +11.89%→-2.46%, JETS +10.77%→-1.74%, ALK +5.92%→-7.61%, AAL +15.70%→-6.32%. DAL (+7.06%→+0.24%) and LUV (+9.35%→+0.23%) both compressed to roughly flat.
• AAL's trend classification downgraded from strong-up to weak-down — the first structural break flagged in this cluster.
• DAL's vs SMA200 extension continued fading: 27.8% (07-10) → 21.8% (07-17), completing a three-scan unwind from the 34.9% monster-tier peak in early July.
• ALK's regime downgraded to downtrend and its distance from 52wk high widened again (-24.98%→-30.92%).

• Does AAL's structural break stabilize, or is this the start of a longer downtrend for the name?
• Is the widened Middle East conflict this week a driver of the sector-wide airline pullback via fuel costs and route risk, or is this a broader market rotation away from the group? This price data can't answer that on its own.
