PAXboy, i understand your concerns, hence why i suggested you complain. You have every right to.
If, not by your choice of course, you ever have to fly FR again, be rest assured there are 5 spare adult life jackets in the a/c. Just ask the PU to give you one.
The more complaints FR get, the more pressure pax will put on them to actually look into the complaints and sort them out.
Wanna e-mail Big MOL? Use surname + forename initial at ryanair dot com (i am not sure i am allowed to post the e-mail address but I'm sure you'll guess my little riddle
)
Rgds,
ATS
