To be honest, its almost impossible to say what new airlines we will have at Birmingham over the next few years.
We can all guess what airlines we would like, and what routes we want served, but you have to consider, firstly is their demand for the route? Destinations like Chisnau, Ashgabat for example would have very little demand, so are not likely to be served. Then the airline in question has to have enough available aircraft to operate the new route, PIA especially don't at present, and are struggling to source engines for their 777 fleet. Then the contract terms at Birmingham have to be acceptable, to both parties. We also have to consider world events, inflation, price, cost, living standards etc
These are reasons why airport can talk to airlines for years, with no new route sucessfully negotiated. We now know we were close to get Play, the airport has mentioned Finnair & Cathy as 2 new carriers/route they would like, Royal Jordanian have hinted at a 2027 start, (still 2 & a half years away), we had Gulf Air annouce BHX many years ago, and then pull out, nothing is ever set in stone in aviation.
We all would like to see the likes of American, Delta, Jet Blue, United, Air Canada, Air Transat on transatlantic routes, the likes of Cathy, Eithad, Gulf Air, Ethiopian etc, and European Airlines, Austrian, Finnair Iberia, ITA, TAP, etc but Birmingham is not the only airport talking to these airlines, competiton is tough, and we still have to remember, we are geographically situated between Manchester and London, large airports that we just can't compete with at present!!
We all have to be patient, and be thankfully for any new airlines that decide to serve Birmingham over the next few years. Fingers crossed we see some new and exciting carriers! 👍
