Appalling Customer Services - avoid at all costs
Flybe has an appalling customer service and try at all costs to squeeze more from customer. In most cases you can't change your flight online within 36h of your flight (i.e. if the check-in has been made) and they phone service operate reduced hours. Result, if you have an emergency in the evening and need to change your early morning flight, forget about it, you will be given a no-show and completely lose your ticket. They won't even let you pay a fee, the booking is wasted.
My son had to be taken to A&E overnight and I tried to change my flight at 1am. Flybe won't let you do it: neither online or over the phone are available. I emailed Flybe be during the night I called customer services the next day. I then emailed Flybe the doctor's prescription as requested and still received a "Sorry, there's nothing we can do, your ticket is voided".
Recommendation: do like many others and just avoid this terrible airline. If not for the tiny planes, bad in-flight service or the minimal overhead storage, do it for the appalling customer services.
