5 Things to Check Before an International Flight
Noa Regev5 min read
The most frustrating travel problems often start with a small detail: a hotel confirmation you cannot open without service, a carry-on that exceeds your fare's allowance, or an entry requirement you assumed had not changed. These five checks cover the trip from your booking details to your arrival. Check passport and entry rules when you begin planning; handle the other items once your itinerary is set.
At a glance: Save your reservations offline, verify baggage and check-in with your airline, arrange mobile service, review insurance coverage, and confirm passport and entry rules for every destination and transit point.
1. Travel documents: Can you access everything offline?
Keep your flight confirmation, boarding pass if issued, lodging address, hotel confirmation, and relevant transit documents together. Confirm that the name on your booking matches your travel document and that dates, airports, and terminals are correct. For a connection or separate tickets, save the booking references for each segment.
Download the files or take screenshots so you can open them without cellular service. Give a travel companion access to a copy, too. A passport photo may help you retrieve its details if needed, but it does not replace the physical passport.
Quick check: Put your phone in airplane mode and try to open the documents. If you cannot, save local copies.
2. Baggage and check-in: What does your fare actually include?
Open your booking on the airline's website or app and check the allowance for a personal item, carry-on, and checked bag separately. Look at the number of pieces, size, and weight for each. Rules vary by airline and fare; for a connection, confirm the operating carrier's rules for each flight. Weigh your bag before leaving home, especially if you plan to bring anything back.
Check when online check-in opens and closes, whether you need to visit a counter, and whether the airline has issued a boarding pass. A booking confirmation is not necessarily a boarding pass. For trips departing Israel, the Israel Airports Authority recommends checking in from home but notes that some airlines do not offer online check-in or issue boarding passes in advance. The same basic action applies wherever you depart: follow the instructions for your airline and specific flight.
Quick check: Compare your packed bags with the allowance shown in your booking, then save your boarding pass after check-in.
3. Connectivity: Will your phone work when you land?
Choose how you will connect before departure: your home carrier's roaming plan, a travel eSIM, a local SIM, or another option that fits your trip. Check destination coverage, data allowance, plan validity, and whether hotspot use is supported. If you need calls or verification texts on your usual number, find out how that line will work abroad and what roaming charges may apply.
For a travel eSIM, confirm that your phone supports it and is unlocked for another carrier. You can start with the eSIM compatibility check. Apple's international eSIM guidance says an iPhone may need Wi-Fi or a hotspot for setup and explains how to check carrier lock status. Follow your provider's installation instructions before you travel, and read the plan terms to learn when its validity period starts; that timing varies by product.
Save your lodging address and route from the airport offline in case mobile service takes time to connect. For device setup, see the eSIM preflight checklist.
Quick check: Make sure your chosen plan covers every place where you expect to use data, including stops between flights.
4. Travel insurance: Does the coverage fit this trip?
Check that the policy dates cover the full trip and that every traveler is named. Read the coverage limits, deductibles, and exclusions relevant to you: preexisting conditions, adventure activities, baggage, cancellation, and trip interruption. Do not assume one type of coverage includes the others. Save the policy number and emergency contact details offline.
The CDC explains that trip cancellation, travel health, and medical evacuation insurance cover different needs. Your usual health plan may also have limited coverage abroad. If you have a medical condition or plan a special activity, ask the insurer what is covered before departure.
Quick check: If you needed medical help at your destination, would you know whom to call and which policy details to provide?
5. Passport and entry: Do you meet each destination's rules?
Check your passport's expiration date, condition, name, and date of birth. Then review visa or electronic travel authorization rules, required passport validity, and any conditions tied to your passport type or reason for travel. Include transit countries where entry or transit rules apply. Do not rely on a universal “six-month rule”: requirements differ by country and itinerary.
The U.S. Department of State's international travel checklist directs travelers to destination-specific passport, visa, and entry information and recommends checking the destination's embassy for current visa rules. The IATA Travel Centre is another useful starting point for passport, visa, and health requirements. Confirm the final requirement with the destination's official authority and your airline, especially if you hold more than one passport or travel on a nonstandard document.
Check health-related entry rules and travel health advice early as well. Vaccination, authorization, and passport renewal can take longer than an evening to arrange.
Quick check: For each destination and transit point, write down the rule that applies to the passport you will use and the official source where you verified it.

Frequently asked questions
When should I check my passport and entry requirements?
Check them as soon as you start planning. Passport validity, visa or travel authorization, and transit rules depend on your destination, route, and travel document. Verify current requirements with the destination’s official authority and your airline so you have time to resolve any issue.
Is a flight booking confirmation the same as a boarding pass?
No. A booking confirmation shows your reservation; a boarding pass is issued after check-in when the airline allows it. Check your airline’s instructions and save the boarding pass offline once it is available.
Which baggage allowance applies if I have a connecting flight?
Check the allowance shown for your fare and each flight segment, including the operating carrier. Compare the permitted number, size, and weight of personal items, carry-ons, and checked bags with what you have packed.
Should I install a travel eSIM before departure?
Check that your phone supports eSIM and is unlocked, then follow your provider’s installation instructions while you still have a reliable connection. Read the plan terms before activating it: the start of the validity period varies by product.
What should I verify in a travel insurance policy?
Make sure the dates and named travelers match your trip. Review coverage limits, deductibles, and exclusions for medical care, planned activities, baggage, cancellation, and trip interruption, and save the policy number and emergency contact offline.
