Passports are required for all passengers embarking on international travel. It is required to have at least 6 months remaining before passport expiration when traveling. Passengers may be denied country entrance or denied boarding if any portion of travel is within 6 months of the passport expiration date.
Condition of passports
In addition to monitoring your passport expiration date, it is important to ensure that your passport is in good condition. Airlines may deny boarding if your passport is not in good condition meaning that the passport is damaged beyond normal wear & tear and/or there is evidence of material alterations. Examples of conditions of passports that may result in denied boarding include passports with significant tears, holes or stains, as well as any changes, obliterations or alterations, or any other damage that affects the integrity of the passport and/or the identification of the holder, such as the name, date of birth, citizenship and document number. If a passport has faded data, is missing data or severely torn, has cut or chewed pages or is missing a cover, missing a picture, requires tape or staples to hold it together, or has been substantially damaged by liquids, chemicals or fire, you may be denied boarding.
