Biman Bangladesh Airlines today urged London-bound passengers to ensure their visas and passports are valid and to update passport details in their UKVI accounts at least 48 hours before travel to avoid delays.

All passengers travelling to the United Kingdom must verify that their visa and passport information is correct and up to date prior to departure, the national flag carrier said in a press release. 

According to instructions from the UK Border Force, it said, failure to update passport or visa details in advance may lead to additional screening, delays or other travel complications upon arrival in the UK.

Biman Bangladesh Airlines requested passengers to complete all required formalities properly before starting their journey to ensure smooth travel, the release added.
