Latvian airline airBaltic has retired its three Avro RJ70s and returned them off-lease to BAE Systems. airBaltic has been building up a fleet of Boeing 737-500s, taking advantage of favorable lease rates, and now has seven examples of the type. YL-BAN (msn E1225) was the first RJ70 to leave the fleet, being withdrawn from service in January and then flown to Exeter for maintenance prior to being handed back to BAE Systems. YL-BAK (msn E1223) followed in February. YL-BAL (msn E1224) operated the airline’s last RJ70 service, on March 5. None of airBaltic’s RJ70s carried the airline’s new color scheme, introduced in November 2004. All three are being advertised for lease by BAE Systems.
