The Flybe flight service from Birmingham (BHX) to Glasgow (GLA) is cheap, regular and dependable.
Flights run six times every weekday, three times every Saturday, and four times every Sunday, with each flight taking no more than 1 hour and 15 minutes.
The cheapest tickets can be found on Flybe's own website (Flybe.com), and, while flexibility on your dates might ensure your ticket price is less than £30 one-way, if you are not flexible you are unlikely to pay more than £45 if you book more than a week in advance. More short notice flights can cost between £60-£100.
For return journeys, you can expect to pay less than £60 if you have flexibility on your travel dates, and £90 if you do not. It is likely, however, that you will find the cheapest deals even with more rigid travel dates, because the vast majority of dates have the same costs if you are able to book several days before your departure.
After you have taken your flight from Birmingham (BHX) to Glasgow (GLA), you might want to transfer into Glasgow city centre.
For this, Glasgow Airport has an excellent shuttle service between the city and the airport, known as Service 500. Running 24 hours every day and taking only 25 minutes, the Service 500 can be caught every 10 minutes from the front of the airport.
Single tickets cost £4.50 and same-day returns cost £6.50. For £7.00 you can purchase an open return, valid for 28 days after purchase, which is an excellent offer for business travellers.
