Budget carrier Ryanair Holdings plc (LON:RYA), which on Friday urged the Republic of Ireland to scrap similar measures, said it would support IAG’s endeavour.

British Airways, which is burning £178mln per week, flew only 485 passenger flights in May.

Its chief executive Alex Cruz previously said the mandatory two-week quarantine impositions to UK inbound travellers are “another blow to our industry”.

Shares in IAG jumped 13% to 326.3p, while Ryanair rose 1% to €12.90 on Friday afternoon.
