The airport is working with airlines and ground handlers to prepare for the festive peak.
It also stated that it is ‘aware of potential strike action at several organisations, including a national Border Force strike.’
To minimise any impact, Heathrow is supporting organisations with contingency plans.
The airport also welcomed airlines, including Loganair and India’s Vistara, with an aim to link the UK with the growing markets globally.
In addition, Heathrow plans to implement changes to its landing fees next year.
Heathrow CEO John Holland-Kaye said: “We have come so far since Omicron grounded Christmas travel plans last year. Heathrow, our airline partners, and their handlers are all working together to make sure everyone can be reunited with their loved ones this Christmas.
Furthermore, Heathrow plans to invest more than £4bn in the next few years, including new security lanes and a new baggage system for Terminal 2.
The airport served 5.9 million passengers in October, which is 84% of 2019 levels. It served 50 million passengers a year to date, representing 74% of 2019 levels.
Its passenger traffic was 19.4 million in 2021, the lowest level since 1972, due to Covid-19-related travel restrictions.
