Wouldn't say FR were too cheap out of MAN. Flew out on a Friday morning to DUB. Returned same day abut 8pm flight back.
Booked for 14 people to travel, came out to £108/person return. I didnt see it as cheap. No hold baggage or even carry on for that fact. I despise using LOCO's. Aer Lingus was cheaper on the day but only 5 seats avail.
