Monarch is not 'bouncing back' with a giant plane order. It's introducing a significant risk and cost to what has become are rather shaky operation.
After a week of ups and downs (mainly downs), they come out and announce they're committing funds to replacing the fleet.
Notwithstanding the fact that the deal may have been done by previous leadership, who can possibly think it's a good idea to introduce an aircraft that does exactly the same as what the current fleet does? If the A321 are too big, get rid and replace them with A320 for which they're all trained to operate.
The company were very quiet and coy over the last week. Yet magically when it comes to splashing (customer's) cash they're singing like a canary.
Utter madness.
