Shares in easyJet LSE:EZJ climbed 12% on Tradegate on Monday after the British budget airline agreed in principle to a £5.5 billion ($7.34 billion) takeover proposal from U.S. investment firm Castlelake over the weekend.

EasyJet, which operates more than 350 aircraft on over 1,200 routes in 37 countries, said on Sunday that it was ready to accept Castlelake's higher bid of £6.90 apiece, potentially ending long negotiations and shaking up Europe's aviation industry.
