We have booked 2 flights for different dates to Belfast from Southampton departing with FlyBe arriving with Aerlingus. When we heard that FlyBe had gone bankrupt, we tried to contact Lastminute to get another outbound flight and request a refund. Nothing. Finally managed to reach them via email and just get an email while they were sorting out the FlyBe flights. After requesting another flight they said nothing was available. We were able to book directly with Aerlingus.
