Good aviation strategy means knowing when to say no, explain why, and offer a better path.

London gets crypto twice this month: @blockworksDAS London Nov 10–11, then @SolanaEvents Breakpoint Nov 15–17.
Thursday to Saturday is free.
Home and back is two Atlantic crossings in four days. A short hop in Europe leaves you fresher.
Doing both, or just one? #Breakpoint2026

@jasonzweigwsj @KCarliniKing @WSJ A Birkin with a serial number qualifies for CBP Form 4457 before you take it abroad from the United States. The certificate is not transferable, and it stays valid only while the signed paper itself remains legible.

@Sothebys Collectors flying to Geneva for Luxury Week with a foreign-origin watch or jewel that has a serial number can register it on CBP Form 4457 before leaving the U.S. Bring the piece to a local CBP office so an officer can match it to the form; CBP does not keep a copy.

Strong planning accounts for airspace restrictions, notices, and slots before problems arise.

@CNBC Family-office principals who travel with foreign-origin watches or jewelry: CBP Form 4457 is how you prove those pieces left the U.S. with you. Register in person before departure; only serial-numbered or permanently marked items qualify.

[Brandon Michael Keene @BrandonMKeene]

@lonelyplanet Starting that trip from the States with a foreign-made camera or watch that has a serial number? Get CBP Form 4457 signed in person before you leave. Only pieces with a permanent unique marking qualify, and foreign repairs stay dutiable even after registration.

[Brandon Michael Keene @BrandonMKeene]

If collectors are flying down from the States with a foreign-made watch or jewelry piece that has a serial number, register it with CBP on Form 4457 before departure. An officer has to compare the item to the form in person, and the signed original is what you show on the way home.

On @ArtBasel Miami Beach VIP days, a walking group cannot exceed six people.

Public days allow twelve. VIP Preview is Dec. 2–3, invitation only.

With the principal, an advisor and security already counted, who else is on the floor list?

@CNTraveler For US guests flying into Istanbul for a wedding: ordinary US passports are visa-exempt for up to 90 days in any 180-day period, but the passport should remain valid at least six months past the entry date. Check that date before anyone books, not at the counter.

[Brandon Michael Keene @BrandonMKeene]

@lonelyplanet From the States, Aspen Mountain and Snowmass list Thanksgiving Day, Nov 26, as opening day. That is a short holiday-week trip, not the same calendar as a mid-December Alps week, so lock which window you are serving before you lock the mountain.

[Brandon Michael Keene @BrandonMKeene]

@MansionGlobal For Americans buying in Spain: ownership does not add stay days. You still get 90 days in any rolling 180 across the whole Schengen area, not Spain alone. I laid out how summer days can cut a Christmas trip to almost nothing here: https://t.co/K0nouw6BDb

Last call for @F1LasVegas race week, per the @FAANews notice:
1. Destination is fixed at takeoff. Within 200 nautical miles of Las Vegas, no change is accepted in the air.
2. File flight plans 4+ hours ahead.
3. Nov 17–24: expect holding or reroutes on arrival.

Summer days in Europe still count in December. The Schengen count looks back 180 days and covers 29 countries as one total (@EUHomeAffairs).
Heading back this winter? Reply "days" and I'll walk you through the check, one passport at a time.

@visitlondon For anyone flying over from the States: Hyde Park Winter Wonderland opens Nov 19, and every guest, toddlers included, needs an entry ticket booked to a one-hour arrival window. The busy slots sell out ahead, so book that hour first and build the rest of the evening around it.

Real due diligence leaves a paper trail showing what was verified before recommendation.

[Brandon Michael Keene @BrandonMKeene]

@CNBC Gifting a first trip to Europe? Since April, the EU's Entry/Exit System (@EUHomeAffairs) takes a face photo and fingerprints from non-EU visitors at their first border crossing, and passports aren't stamped. That first arrival runs long, so skip a tight connection after it.

Landing in Japan between December 21 and January 4 with a medicine Japan treats as a narcotic, like oxycodone or Vyvanse? The complete permission papers are due December 7, and the traveler has to carry the medicine personally.
What @MHLWitter and @mohapuae ask for, in plain words:
