Travel Documentation
Passports and visas
Every international journey needs the right documents: passport, visa or e-visa, transit visa, and sometimes an onward ticket or proof of funds. Many countries require a passport valid for six months beyond arrival or return, and some require blank pages. Visa rules depend on nationality, purpose and length of stay - check the destination's official source rather than relying on a GDS message alone.
Other documents
Know ESTA (USA), eTA (Canada), ETIAS (EU, when operational), UK ETA, and health documentation such as yellow fever certificates for certain countries. Minors may need parental consent letters. Airlines transmit Advance Passenger Information (API) and PNR data. The Schengen area allows many nationalities 90 days in any 180-day period.
Traps
Common errors: assuming a visa guarantees entry (the border officer decides), forgetting transit visas for connections, and miscalculating the 90/180 rule. Passport validity is counted from entry or return depending on the country - check both.
Worked example
A traveller enters Schengen on 1 March after spending 10 days there in January. The 180-day lookback window starts around 3 September of the previous year; the January days count against the 90-day allowance, so the March trip has 80 days left, not 90. Rule of thumb: count all Schengen days in the rolling window, not just the current trip.
Industry Regulations
Who regulates what
ICAO sets international standards through the Annexes to the Chicago Convention, covering safety, security, facilitation and the environment; national civil aviation authorities (FAA, EASA, CAA) implement them. IATA is a trade association: it sets commercial standards (resolutions, BSP, dangerous goods rules) but is not a government regulator. The Warsaw Convention and its successor, the Montreal Convention 1999, govern carrier liability for death, injury, delay and baggage, with limits reviewed periodically. EU Regulation 261/2004 provides compensation and assistance for delays, cancellations and denied boarding on qualifying flights.
Consumer and data rules
Package Travel Regulations protect package holidaymakers; the UK's ATOL scheme and similar bonding protect against insolvency. Data protection (GDPR/UK GDPR) governs how PNR and customer data are used. Disability regulations require assistance for reduced-mobility passengers.
Traps
Do not confuse Montreal (liability) with EU261 (compensation). EU261 applies to flights departing the EU/UK plus EU/UK carriers arriving, and "extraordinary circumstances" can remove compensation but not the duty of care. Do not call IATA a regulator.
Worked example
A four-hour delay on a 2,000 km flight: under EU261, compensation may be €400 plus assistance, unless the cause is extraordinary. Under Montreal, delay damages are separate and require proven loss. Rule of thumb: identify which regime applies before quoting any entitlement.
Safety and Security
Layers of security
Aviation security follows ICAO Annex 17: access control, screening of passengers and baggage, cockpit door protection and security intelligence. Know restrictions on liquids, aerosols and gels (typically 100 ml containers in a 1-litre bag), sharp objects, and the rules on powders and large electronics in some jurisdictions. Dangerous goods are governed by the IATA Dangerous Goods Regulations, based on the ICAO Technical Instructions: lithium batteries, aerosols, flammable and toxic items.
Health and destination risk
Travel advisers should check FCDO or State Department advisories, health requirements (vaccinations, malaria, yellow fever) and local laws. Crisis management means knowing evacuation procedures, consular contacts and 24-hour support. Duty of care includes pre-trip risk assessment.
Traps
Batteries: spare lithium batteries and power banks must travel in cabin baggage, not checked, and are often limited in capacity (e.g. 100 Wh, with approval up to 160 Wh). Matches and lighters have specific rules. Do not assume a connecting passenger avoids security screening.
Worked example
A client wants to pack a 20,000 mAh power bank (about 74 Wh) in checked baggage. Correct advice: keep it in the cabin, terminals protected, and check the airline's limit. Rule of thumb: if it stores energy and is spare, it goes in the cabin.
