JetBlue said the ticking fee, which would give Spirit shareholders a monthly prepayment of 10 cents per share between January 2023 and the closing of the deal, bumps up the total price for Spirit to $34.15 per share.

JetBlue last week had sweetened its takeover offer for Spirit to $33.50 per share.
