No, the Association of Flight Attendants-CWA cannot block President Trump's proposed arch over safety concerns. It has no veto power, so its warning can add pressure but cannot stop construction by itself.
The Association of Flight Attendants-CWA is a labor union for cabin crews, not the airport operator. Its warning says the 250-foot arch at Memorial Circle would sit in the final approach to Reagan National Airport (DCA). According to CNN Politics, the FAA found no substantial adverse effect on airspace but required added lighting for visibility FAA safety decision.

What the union warned
The union issued its warning on Oct. 7-8, 2026. According to the Association of Flight Attendants-CWA, the arch would place a new obstacle in the DCA flight path in its safety alert. AFA President Sara Nelson said DCA is already stretched to its limit.
AVweb reported she pointed to unaddressed risks after the Jan. 29, 2025 midair collision over the Potomac. That crash of American Airlines 5342 and Army helicopter PAT 25 killed 67 people. The union represents about 55,000 flight attendants at 20 airlines. AVweb reported that scope means the warning reflects cabin crews who fly DCA daily, not residents or the airport operator.
Why regulators still cleared the site
The proposal calls for a 250-foot arch at Memorial Circle. AirlineGeeks described the site as less than two miles north of DCA near Arlington National Cemetery. The design takes its model from Paris' Arc de Triomphe.
CNN Politics reported the FAA review did not block the plan. It found no substantial adverse effect on navigable airspace. Approval was conditioned on red obstruction lighting, floodlighting and a non-standard eternal flame for pilot visibility.

Who holds the blocking power?
The union cannot issue a veto. According to AVweb, the FAA determination stayed open to petitions for review through October in its airspace review update. According to the same report, the final build decision rests with the National Park Service, not AFA-CWA.
That split matters for readers tracking accountability. A safety objection alone does not change the legal status. Readers can watch the Park Service decision and any court orders, not union announcements, for the binding result. Petitions challenging the FAA determination were the direct route during the October review window.
- FAA airspace finding – open to formal petitions, not union statements.
- National Park Service – makes the final build decision.
- Courts – can pause or vacate approvals.
- Union warning – advisory pressure for reforms and oversight.
Which lawsuits could stop construction?
Arlington County, Virginia sued Interior and the Park Service on Oct. 8, 2026 in the Eastern District of Virginia. According to Northern Virginia Magazine, the county alleges rushed review in its lawsuit report. It argues an Environmental Assessment violates the National Environmental Policy Act, which requires a full Environmental Impact Statement.
Three veterans and an architectural historian filed a separate case in D.C. The Palm Beach Post reported they argue Congress must authorize the memorial. Judge Tanya Chutkan ordered on Sept. 4, 2026 that the administration give 48 hours' notice before construction-related work at Memorial Circle.
