I was booking flights with KLM and noticed that from this Sunday, Belfast flights will be upgraded to the E190 on selected days. The current schedule is as follows;
E190: 26th March - 9th April, 1st May - 14th May, every Sunday from 21st May
F70: 10th April - 30th April
E175: Monday - Saturday from 15th May
I'd say the prolonged E190 periods will be due to operational reasons - lack of F70/E175 - or possibly something to do with Embraer crew training at BHD.
The Fokker 70 will leave Belfast for the final time on 30th April.
The Sunday upgrade plus the extra capacity of the E175 over the F70 means that there will be 68 extra weekly seats each way on the route.
