RE. EMA Flights.
During summer it is perfectly normal for airlines to reduce certain routes. I believe this is what is happening with the EMA flights. Its continually a bread and butter route for T3 as is NCL-BHX. And no you cant fly from BHX for a 1/4 of the price.
The E135 may be unloved, but its a perfect size for T3's niche business model. The company can now cater for charter markets 29 (JS41), 37 (EMB135) and the 50 (SAAB2000). The charter scene for this sort of capacity is deeply underserved at the moment.
