Lithunain Airlines (LAL) will change two of it's leased Boeing 737-300 ("Žemaitis" and "Antanas Gustaitis") and lease two Boeing 737-500 instead. Lithuanian Airlines already used one Boeing 737-500 a while ago, but then terminated the lease and changed it with old Yakovlev Yak-42, which was gotten back from lease to some mid eastern airline. Now LAL retired all Yakovelevs and completely westernised it's fleet. Current LAL fleet is:
2x Boeing 737-300 (both leased, flying mostly to Western Europe, to be changed to 737-500)
2x Boeing 737-200 (both owned, flying to non-EU countries like Russia, Ukraine, also on charter flights)
3x SAAB 2000 (all leased, flying to Scandinavia and some shorter destinations like Tallin, etc.)
Formerly LAL also had 2 Yak-42 (owned), which were changed to 1 737-300 (previously LAL had only one plane of this type) and 1 SAAB-2000. Also LAL owned two very small SAAB-340B, but it decided that flights with such small aircraft should be carried by it's subsidary Air Lithuania, which uses two ATR-42 and flights from two other airports, Kaunas and Palanga. Both Yaks were sold to other Lithuanian airline, Aurela.
