Indeed could be said the B737-8200 entered service FROM Stansted today with EI-HEZ to Bergamo...since returning.
EI-HEN operated the first ever B737-8200 commercial flight for RYR on the evening of 23.6 when it flew a DUB-STN service.
EI-HEZ operated the morning DUB-STN service yesterday 25.6.
Both a/c based now STN.
