Very similar
From what I remember very similar. However the Nouvelair was operated by Air Comet with a Tunisian flight attendant to make anouncements and sell duty free.
Asked for seats near the front on both and got an entire row of the then Aer Lingus business class seats to ourselves and were accosted by a staff member on Nouvelair return and dumped in business class seats due to young child.
Hot meal on both airlines, usual pay for drinks - minimal delays and friendly staff.
However remember this was an Aer Lingus charter and before their cutbacks!
