Back in 2018 at the depths of their troubles they had already got loans on the basis of one out of the few airframes they owned. They don't have enough clapped out decade old Q400s to get loans.

When asked for a comment on the current state of negotiations and the speculation that a deal was imminent, a rather terse "Flybe doesn’t comment on these matters." was all we were given, which doesn't clarify the muddy waters. The firm has however been rather busy scrubbing around for various sources of financing in the last two weeks which has included getting another loan or mortgage on one of its Bombardier Q400 turboprop aircraft - G-JEDW that netted £5 million ($6.35million). The sale of a hangar at Exeter Airport (EXT), which Flybe will now lease back raised a further £5 million of much-needed funds. The company is also in dispute with Monarch Aircraft Engineering for maintenance contracts at Birmingham and Manchester, which may save the carrier some cash, although it will have to do all the maintenance itself, which might negate any cost savings.
