Irish airline Aer Lingus is expected to accept a bid from British Airways owner IAG.
Last year, the airline had rejected two bids from IAG, who also control Iberia in Spain.
The new offer is thought to be for around €2.50 per share (£1.87). It would value Aer Lingus at around €1.3 billon (£971 million).
Currently, Ryanair have a 29.8% share in the airline, while the Irish government own 25%.
The deal would give IAG more take-off and landing slots at Heathrow Airport, allowing it to operate more more flights. The slots are valued at around £30 million per pair.
Simon Calder, Travel Correspondent for the Independent, joined Wake Up London to discuss the deal and what impact it will have for travellers.
