Hello all, this is my first post because you all answered my other questions in advance

Thanks !
I booked 2 x F award tickets MAN-FRA-EZE,for, 16/4/08 & 10/9/08 about 1 year in advance, then in December the schedule changed MAN-FRA bringing the connection time down from 45 to 35 min. They rebooked me on previous days evening flight without consulting me, i emailed them & spoke to SEN line, SEN line said ok as its VERY inconvenient to fly a day earlier & i do not want to pay for overnight stay

. Now M&M have called me & say i have to change, can they do this ?
Any advice appreciated, Regards, Chris
