The carrier has further relaxed its mask mandate after the Welsh government eased its Covid restrictions on Monday (28 March).
Tui dropped its face mask mandate on all services to and from England and Northern Ireland on 11 March.
However, it continues to recommend – in line with UK government guidance – that passengers continue to wear face coverings during their flights.
Face coverings remain mandatory for all passengers aged 12 and above flying to and from Scotland, unless medically exempt.
Tui on Monday also warned passengers to be mindful of destination-specific mask rules, such as those for flights to the US and Italy.
