The Mahfudh (correct) narration from 'Aishah (RA) (concerning this matter) is that it was her practice (that she (RA) offered prayers in the complete form during travelling) [and not the practice of the Prophet (ﷺ)]. She said:

'It is not hard for me.' [al-Baihaqi reported it].

وَالْمَحْفُوظُ عَنْ عَائِشَةَ مِنْ فِعْلِهَا, وَقَالَتْ: { إِنَّهُ لَا يَشُقُّ عَلَيَّ } أَخْرَجَهُ اَلْبَيْهَقِيّ ُ [1]‏ .‏
