Rules and border changes
EU Entry/Exit System launches October 12, 2025
A major change is coming to how non-EU travelers enter Europe. Beginning this October, the new EU Entry/Exit System (EES) will replace passport stamping with a digital process. For most US visitors, that means a fingerprint and facial scan at the first point of entry — whether that’s Paris, Frankfurt, or Rome.
The rollout runs through April 2026, and while the goal is faster crossings long term, travelers can expect longer lines this winter as airports adapt to new procedures. The winter 2025–26 is the first full season affected by EES. For many Americans flying to Europe for the holidays or early spring trips, it could shape how smoothly the journey begins.
What to do: Build in extra time at your first European airport and head straight to the official EES kiosks. Frequent flyers with Global Entry or concierge services should confirm if dedicated EES assistance is available.
Traveler tip: Check that your passport’s photo page and biometric chip are in good condition — worn or damaged documents are the main reason EES kiosks reject scans.
UK Electronic Travel Authorization now required for US visitors
The UK’s Electronic Travel Authorization (ETA) system is now live and applies to most short-term visitors — including US citizens traveling for tourism or transit. The digital permit costs £16 (~$21) and must be obtained before departure, even if you’re only connecting through a UK airport and will clear border control.
The winter 2025–26 is the first season when many frequent flyers will encounter the new requirement — and missing it could mean denied boarding.
What to do: Add the ETA to your UK trip checklist, and don’t overlook same-airport connections that require passing through immigration.
Traveler tip: Apply online at least 48 hours before your flight and use the official UK ETA website or app — third-party services often charge unnecessary fees.
REAL ID now required for US domestic flights
Starting May 7, 2025, all US travelers aged 18 and older must show a REAL ID-compliant driver’s license (or another TSA-approved ID such as a passport or military ID) to board domestic flights. This requirement will be fully enforced by the time the winter 2025–26 travel season begins.
It’s easy to overlook amid international headlines, but this update affects every domestic flier — especially those connecting through US hubs on international itineraries.
What to do: Verify that your driver’s license or state ID shows the REAL ID star marking. If not, upgrade now or plan to travel with your passport or another accepted ID.
Traveler tip: Even with a REAL ID, carrying a passport or trusted-traveler card can help avoid delays at TSA checkpoints during peak holiday travel.
Cabin upgrades
United unveils next-generation Polaris interiors
United Airlines is rolling out its redesigned 787-9 Dreamliner cabins through 2026 — a two-tier upgrade that redefines premium travel. The refreshed Polaris cabin now features privacy doors, 19-inch 4K screens, and upgraded materials. The all-new Polaris Studio elevates the front-row experience with 27-inch displays, caviar service, and enhanced personal storage.
The winter 2025–26 marks the first phase of United’s premium transformation — and early aircraft assignments will start appearing in schedules as travelers plan spring and summer 2026 journeys. Early routes to watch include San Francisco–Singapore and San Francisco–London, both expected to debut the new interiors in early 2026.
What to do: For early 2026 trans-Pacific or Europe trips, monitor aircraft types on SFO long-hauls and secure Polaris Studio seating when available — demand is expected to surge once travelers experience the difference.
Traveler tip: On routes with mixed 787-9 fleets, look for aircraft listed as “new interior” or “enhanced Polaris” during seat selection — it’s your cue that the upgrade has arrived. Or simply let AranGrant’s agents know, and we’ll make sure your itinerary features the newest cabin available.
American expands its Flagship Suite® experience
American Airlines continues the rollout of its Flagship Suite® cabin this winter, extending its refreshed 787-9 Dreamliners across more long-haul routes. The upgraded aircraft feature fully enclosed business-class suites with doors, reimagined finishes. A revamped Premium Economy offers larger inflight-entertainment screens, footrests, and additional storage.
Expect expanded service to Australia, New Zealand, and South America, along with increased London Heathrow frequencies by late 2025.
What to do: Prioritize AA 787-9 aircraft for winter long-hauls to secure the new Flagship Suite® or enhanced Premium Economy seats — both deliver a noticeably elevated experience over legacy cabins.
Traveler tip: When booking, review the aircraft details under “seat information.” If you see mentions of suite doors or a redesigned business-class layout, you’re looking at the newest Flagship Suite® cabin. Or, to make it effortless, let our agents know — we’ll secure seats on the upgraded aircraft for you.
Delta refines its Delta One Suite experience
Delta Air Lines continues advancing its widebody cabin refresh. Expect gradual upgrades across A350-900 aircraft and the introduction of new A350-1000s beginning in 2026. Rather than a single rollout, enhancements are being phased in — featuring refined Delta One Suites with upgraded privacy doors, softer lighting, and elevated materials.
We include this update in the winter 2025–26 outlook because many of these refreshed aircraft will begin appearing on key trans-Atlantic and trans-Pacific routes during this season.
What to do: Verify the aircraft subtype before booking — A350-900 (new layout) or A350-1000 signals the latest suite design. Or let us know, and we’ll secure your itinerary on Delta’s upgraded cabins.
Traveler tip: For the best chance of the newest Delta One Suite, check flights departing from Atlanta or Detroit — they’re among the first hubs to see refreshed aircraft.
Economy cabins quietly step up in comfort
Even in economy, travelers will notice subtle but welcome improvements this season. United, Delta, and JetBlue are rolling out ergonomic slimline seats with a touch more legroom in the forward rows, smoother recline mechanisms, and 13-inch 4K seat-back screens on new or retrofitted aircraft.
The goal: to narrow the comfort gap between Economy and Premium Economy without raising fares too sharply. Many of these refreshed cabins are entering service now — just as long-haul leisure travel hits its seasonal peak.
What to do: When planning long-haul trips, look for aircraft labeled “new interior” or “Next Gen cabin” — they typically feature the latest seats and screens even in standard Economy.
Traveler tip: On United and Delta, seat maps showing larger seatback screens or updated cabin visuals usually indicate the newest interiors — worth checking before you book.
Lounges and access policy shifts
- United expands its Polaris Lounge in Chicago (ORD): United’s flagship Polaris Lounge at Chicago O’Hare received a major 2025 expansion, adding more seating and an upgraded à la carte dining area. It’s now among the most comfortable hubs in United’s network for premium travelers.
- Chase Sapphire Lounges ramp up nationwide: The Chase Sapphire Lounge network continues its rapid growth, with Philadelphia (PHL) opened in February 2025 and new lounges coming to Las Vegas (LAS) mid-year and Los Angeles (LAX) by late 2025. Together, they expand premium coverage for Sapphire Reserve cardholders beyond East Coast markets.
- Amex brings Centurion access to Salt Lake City: American Express adds Salt Lake City (SLC) to its Centurion Lounge map in 2025, just in time for winter ski season. Systemwide, expect refreshed menus and smoother food-and-beverage service as part of this year’s upgrade initiative.
- Capital One tightens lounge guest policies: Starting early 2026, Capital One Lounges will introduce new restrictions on guest access and revise authorized-user entry rules for Venture X cardholders. Complimentary guesting will no longer apply to all visits.
Network moves for winter demand
United Airlines
Starting January 2026, United will add capacity on more than 15 domestic routes, including Fort Lauderdale, Orlando, and Las Vegas — part of a broader strategy to capture strong winter and early-spring leisure demand. The move includes additional daily frequencies and larger aircraft on select trunk routes.
Traveler tip: Routes from Chicago, Newark, and Houston are leading this expansion — ideal gateways for pairing domestic winter escapes with same-day international departures.
Delta Airlines
Delta is adding fresh lift where it matters most this winter — from Atlanta to St. Vincent and Grenada, giving travelers rare nonstop access to two sought-after Caribbean islands. The carrier will also operate a second daily New York (JFK)–Tel Aviv flight from November 30, 2025, through January 19, 2026, to accommodate peak-season traffic.
In addition, Delta will inaugurate Atlanta–Marrakech (RAK) service on October 25, 2025, operating three times weekly — marking the first-ever nonstop flight from the US to Morocco’s Red City.
Traveler tips: Delta’s new Caribbean services from Atlanta connect smoothly to long-haul premium itineraries — perfect for adding a short island break to a larger winter trip. Also, keep in mind that Marrakech’s mild winter climate makes it ideal for a November cultural break or a desert extension before European holiday crowds arrive.
JetBlue
JetBlue is expanding its Florida network this season with multiple new and returning routes from Fort Lauderdale (FLL) — including San Pedro Sula (SAP), St. Maarten (SXM), and Grand Cayman (GCM) — all launching on December 4, 2025. The airline is also introducing new Daytona Beach connections on the same date, further strengthening regional access ahead of the holiday surge.
Traveler tip: Early December launches often carry introductory fares and extra award availability, making this a prime window for booking winter sunshine getaways.

Loyalty program notes
- Delta SkyMiles holds steady for 2026: For once, no new hurdles: Delta has confirmed that 2025 Medallion Qualification Dollar (MQD) thresholds will remain unchanged for the 2026 status year. After recent adjustments, this stability is welcome news for frequent flyers planning their next qualification cycle.
- United MileagePlus adjusts behind the scenes: United continues to fine-tune MileagePlus. There are minor but notable changes: upgrade charts and information are moving off the public site, and PlusPoints earning and qualification are tightening for 2025–26. While not dramatic, these shifts reduce visibility for travelers tracking upgrades and elite progress. Set clear expectations — upgrade details may be harder to find. Keeping an eye on PQP/PQF calculations will help avoid surprises near status thresholds.
- American AAdvantage adds partners and refines upgrades: American Airlines expands its reach through new and upcoming partner accruals, now including Fiji Airways and soon Oman Air via oneworld. At the same time, systemwide upgrade (SWU) validity rules are changing from March 1, 2025, aligning usage windows with the membership year.
As the skies shift and new routes, cabins, and benefits take shape, this winter invites travelers to fly smarter — and savor every moment along the way. Wherever the season leads you, may your journeys be cozy, pleasant, and memorable with AranGrant — your trusted portal to the best premium class flight deals.
