March is one of the busiest travel months of the year, and this one has a few extra wrinkles. The DHS shutdown has left some airports short-staffed at TSA checkpoints just as spring break volume picks up. Overseas, the Iran conflict has disrupted airspace across parts of the Middle East. Neither of these affects every traveler equally — but a little preparation goes a long way toward making sure they don't affect you at all.
1. Give yourself more time at the airport
The partial DHS shutdown has begun affecting airport operations. With TSA officers working without full pay, callouts are rising at some locations. CNN reported waits past three hours at Houston Hobby recently, with extended lines also reported at New Orleans, Atlanta, Charlotte, and Bush Intercontinental.
Most of the country's 430-plus commercial airports are running normally. But the ones under pressure are seeing real delays, and it's hard to predict which airports will be affected on any given day. The move here is simple: check your specific airport's wait times before you leave the house. The FAA also publishes a real-time dashboard of every active ground stop and delay program in the country at nasstatus.faa.gov — it's the same feed air traffic controllers use, and it takes ten seconds to check before you head out. TSA PreCheck remains operational and worth using. Global Entry is suspended nationwide, so if you're returning from abroad, plan for the standard CBP line.
2. Book the earlier flight
The Department of Transportation notes that early-morning flights are less susceptible to delays, that connections increase the risk of a misconnection if the first leg runs late, and that earlier departures generally leave you with more rebooking options if something does go wrong.
There's data behind the instinct, too. According to Google's aggregated flight pricing data, midweek departures run about 13% cheaper than weekend flights — and during spring break, that gap can exceed $60 per ticket. The safer flight and the cheaper flight are often the same flight.
When two options cost roughly the same, the earlier departure with the calmer connection is almost always the smarter pick — especially in a month with this many moving parts. One thing worth doing if you're comparing itineraries: check whether your layover requires a terminal change. A 55-minute connection at a single-terminal airport is comfortable. The same 55 minutes at JFK with a terminal transfer and a train ride is a coin flip. Airlines will sell you both, and the booking page won't distinguish between them.
3. Cruisers: arrive early and check your itinerary
Cruise travel works differently from almost any other kind of trip. A late hotel check-in is an inconvenience. A missed embarkation means the ship sails without you.
Cruise Critic says it plainly: if you're flying to your port, arrive at least one day before departure. That pre-cruise hotel night gives you a real buffer against flight delays, cancellations, and rerouting — and it's one of the smallest investments you can make for the most peace of mind.
There's also a second thing worth knowing for Caribbean sailings: some itineraries are shifting. Royal Caribbean has suspended all visits to Labadee, Haiti for the remainder of 2026 due to security concerns. Norwegian has skipped port calls in Curacao tied to the Venezuela situation, and Southern Caribbean sailings near Aruba and Trinidad may see further adjustments. Lines are rerouting to Nassau, Cozumel, and their private islands. Check your cruise line's travel updates page before you pack so you know exactly what to expect.
For international sailings, one more thing: the CDC recently issued a Level 2 advisory covering 32 countries — including Germany, Spain, and the UK — for a circulating poliovirus outbreak. The recommendation is to confirm you're current on polio vaccinations before you go, with the option of a single lifetime booster. Not a reason to cancel anything, but if your Mediterranean itinerary touches three affected countries, five minutes checking your vaccination records now saves a conversation with a ship's medical officer later.
4. Solve customs before you go
Most travelers put all their planning energy into the outbound trip and forget about getting back in. With Global Entry suspended and staffing stretched, the return through customs is worth a few minutes of prep.
CBP's free Mobile Passport Control app lets eligible travelers submit their information up to four hours before landing or immediately after. It covers 53 ports of entry, including 14 preclearance locations and four seaports — and with Global Entry offline, it's one of the best tools available for a smoother re-entry.
If you're heading to Mexico specifically, it's worth knowing that the State Department's overall advisory is Level 2 — "Exercise Increased Caution." That's the same classification as France, Italy, Germany, Spain, and the UK. The difference is that Mexico's advisory is broken down by state: Cancún, Mexico City, and Oaxaca sit at Level 2, while Yucatán and Campeche are Level 1. The smart move is to read the state-by-state breakdown rather than just the headlines, and enroll in the State Department's free Smart Traveler Enrollment Program (STEP) so the embassy can reach you if anything changes.
5. Your carry-on is your lifeline
When travel days get complicated, small problems compound. A longer security line tightens your boarding window. A tighter boarding window means less overhead space. A delayed first leg turns a comfortable connection into a close one.
The fix is easy: keep your real essentials — medication, chargers, documents, anything you'd hate to be separated from — in your personal item and carry-on, not buried in a checked bag in the cargo hold. That way, even if the day doesn't go to plan, you're still in good shape. One thing worth double-checking before you book: basic economy fares on several major U.S. airlines now restrict you to a personal item only — no guaranteed overhead bin access for a carry-on. If your whole strategy is keeping essentials close, make sure your fare actually allows you to bring them on board.
One more thing worth doing before any international trip this month: look into "cancel for any reason" travel insurance. Standard policies generally won't cover disruptions from events already underway, and demand for CFAR coverage has surged. It's a small upfront cost that can save you from absorbing a nonrefundable itinerary if plans change suddenly.
The bottom line
March travel has more variables than usual — but none of them are unsolvable. Check your airport, book the earlier flight, arrive at your port a day ahead, set up your re-entry tools, and keep your essentials close. A little planning now means a much smoother trip later.
