Bombardier said on Tuesday that Egypt Air had signed a letter of intent to purchase 24 CS300 jets from the Canadian company.
Bombardier Commercial Aircraft President Fred Cromer announced the agreement at a news conference at the Dubai Airshow.
Meanwhile, Airbus said on Tuesday it had signed a preliminary agreement to sell 25 A320neo aircraft to Golden Falcon Aviation, the exclusive aircraft supplier to Wataniya Airways of Kuwait.
The memorandum of understanding, worth $2.7 billion at list prices, was signed at the Dubai Airshow.
Wataniya Airways resumed flights in July, six years after ceasing operations due to its financial situation and political instability in the Middle East.
