Jet2.com don't fly to TXL & never have. TXL=Berlin Tegel).
The Jet2 flights go to Berlin Schonefeld SXF.
Yes, the SXF flights were on for the winter, expensive too, I thought. Looks like its been pulled.
Good news for German fans though.........Air Berlin are to continue the Hamburg service through winter, bookable now from £1, despite the check in staff only last week telling me its scrubbed.
