Booking Flights & Flying: A Beginner’s Guide to Avoiding Pitfalls

Cabin-bag rules, liquid limits and low-cost-carrier fine print — from booking to boarding.　6 min read · Updated 2026-10-31

5 things to check before you book

• Passport validity: many countries require at least 6 months’ validity on arrival — check your destination’s rules.
• Your name must match your passport exactly; fixing typos usually costs money or a new ticket.
• Allow enough connection time: if you change airlines or must re-check bags, leave 3+ hours.
• Read what the fare includes — checked bags, meals and seat selection are often extra on low-cost carriers.
• Know the change and refund rules; if your plans may shift, choose a flexible fare.

How the airport process works

• Arrive 2.5–3 hours before an international flight, earlier in peak season or at busy hubs.
• Online check-in and seat selection save time, but checked bags still go to the counter.
• Liquids, gels and sprays in the cabin are usually limited to 100 ml per item in a 1-litre clear bag — check your airports’ and airline’s rules.
• Power banks and lithium batteries must go in hand luggage; capacity limits vary by airline.
• Check rules for knives, lighters and other restricted items to avoid confiscation or delays.

Low-cost carrier traps

• Strict weight and size limits — paying at the counter is expensive, so pre-book bags.
• Check-in counters close on time; arrive late and you may not fly.
• Food and drinks on board cost extra — bring snacks for long flights.
• Compensation for delays is limited; consider travel-delay insurance.

Final pre-flight check

• Passport, tickets and hotel bookings (file + screenshot)
• Phone charged, power bank in your carry-on
• SIM / eSIM set up
• Essential medication in your hand luggage
